Title: LML Duramax build Part 5
Post by: Flyin6 on April 05, 2018, 10:42:23 PM
As Nate accurately predicted, with the start of this new round of modifications to the 2011 Silverado, I'll start part five in this long running series.

So at the moment, I have owned the truck a bit more than 6 1/2 years and the truck still has less than 90,000 miles, I think in the 88,500 mile range. It continues to tow all the time, and is used off road pretty much every week. Today was no exception. The truck as of this writing is covered in mud, which is really more the norm for this Silverado than being clean. The paint is holding up well, although now there is a pretty good coverage of rock chips and a couple very small dings, from hitting deer, a buzzard, a couple other things and running into trees and the like more times than I can recall.

Anyway, to allow for another couple hundred thousand miles of use, I decided to replace the problematic CP4.2 high pressure pump, and while I was at it, go for an upgraded turbocharger.

I procured all of that from Diesel Ops of Michigan and the new tune from Motor Ops of Ontario, Canada. They wrote me a new tune and I have already downloaded it into my laptop, and will soon complete its journey into the truck via the downloader.

Today marks the point where the final parts came in. All the Fleece stuff was piled up outside the garage door when we all got in from a hard day's work at the farm.

Three big boxes:

The long box contained the new down pipe. along with some of the parts used in the S-362 TurboCharger conversion. The stainless pedestal is impressive and very heavy!

Post by: Flyin6 on April 05, 2018, 10:46:10 PM
Next box contained the heavy and large turbocharger, the Fleece S-362 unit which should make along with the pump and the tune some 625 rear wheel horsepower.

The the parts kit for the CP3 conversion. It is said to be a complete kit, requiring nothing else except time and effort to install
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 05, 2018, 10:48:53 PM
This new CP3 high pressure fuel pump was modified by Fleece to continue to supply fuel above 3,000 RPM. Factory units do not do that, but will start to pull fuel off above the 3K threshold.

With the oil, filters, heat shield from summit, all the chems and sundry items, along with the Fleece parts I am right at $4K, and on to $4,150 including the new tune.

I am planning for a few days labor to complete

What was the cost on that upgraded CP3 from Fleece by itself? The CP3 pump on my truck decided to grenade at 171k miles, and the used unit I had put in (shop told me they have replaced only 2 CP3 pumps before since the Duramax came out in 2001, and they service entire fleets of these things) is now weak and not pushing enough rail pressure at WOT. If the upgraded pump isn't much more than refurb OEM, I may as well go that route. Cheers.

I'm about to set up something with Diesel Ops for members here if you order from the supplied link which may save you something. He gives 10% off if you are military, subject to limits (Sometimes they don't have 10% margin)
But you can get the modified CP3K LML kit for around $1600

If it’s the same I’m maybe interested chief.

I think the LML with the variable guide inlet vanes is different than earlier turbos. Can someone verify this?

OK, need advice from the brain trust (Shawn, that means you remain silent!)
So, Ken...
Getting ready to start this CP3 conversion.
My question is that since I am going to be torn down should I take advantage of this time to:

1. Replace the water pump
2. Replace the belt idler
3. Replace the fan belt
4. Replace the lower/upper radiator hoses

The truck's build date is late 2011
It has 89,400 miles on the clock
There was a possible weeping lower hose issue last winter with near zero temps, but has not duplicated since tightening rad hose clamps.

Opinions from D-Max owners/those knowledgeable??

I couldn't do the GM parts, as in from Chevy

Just too costly!

I have very deep discounts at O'Reilleys that sometimes knock 50% off my bill. But looking at the website prices, I am appalled!
Like $248 for the lower hose!!!!!!!!!!
$70 or $142 for the pump. $40 for the upper hose.
Haven't priced the idler, but I'm sure it isn't free!
Wow, is it just me, or has life in the 'merica gotten really expensive the past 5-7 years.
I am starting to get shocked by the cost of lumber, it's on a death spiral upward.
And grass seed. I was told that due to some drought somewhere, 50 lbs of KY #31 was going up to over $100 Last year it was in the $30's

I am with ken in the T-Stats,

as far as the waterpump, wasnt there  some sort of an upgrade offered a few years ago that had to do with welding the impeller or something like that or am thinking of something different?

I have a few more years and miles on the clock with more drastic temp changes up and down, I wouldn’t stress about the hoses. But a belt and pulleys are easy to do now or later.

I can probably find some T-Stats that are GM, maybe a water pump...

Ken/others. What should I be paying for these parts:

Pump?
Lower hose?
Upper hose?
T-stats?
Idler?

I don't think the welded shaft on the water pump is as big a problem as the cases being eaten away in 80K-100K

I'll know soon enough, but I was thinking $75 ish so why not. But at these very high prices, man, it's just cutting into my budget big time!
But, I do plan to operate this truck until maybe 2023 as a prime mover, so I want it to be pretty reliable.

But if my rich uncle dies in the poor house between now and then, I'll likely buy something smaller to scoot around in (Always like that 4cyl D-Max ZR2) and save C-max for the work which it just gobbles up.

Looks like I get to redo the axle seal on the driver side of my truck, gear box is getting lots of play side to side on the shaft, plus a new leak from one of the cold pipes to the inter cooler.

The better upgrade for the pump is the pinned version, so welding to heat seals etc.  I believe Danville made the one for my LB7 which is an OEM AC delco but they drill and pin the impeller to the shaft.

OK, I checked out that hose from Summit, I called them
They could not guarantee that the referenced part JR spec'd which was for a 2006 would fit. They could not source me a lower hose at all from anyone!

But from Amazon I found a new AC Delco water pump, some AC Delco thermostats, an idler puller, tensioner and gasket, all delco parts, and a new belt for my dual alternator truck and a couple other things.

My plan will be to use these parts but keep the stock hoses for now.

Oh and a call to O'Reilly's on the lower hose: Special order, $166 and be here in like 10 days. So, I'll get the hoses on before winter, but for now, let's get this thing torn into and get this new pump on!

In general, be careful when buying AC Delco. They have 3 different quality lines, replacement, "professional" and OEM. IIRC.  Stay with OEM and you're OK.  The others are low cost lines to compete with aftermarket.

Anyway, just back from Best Buys

Good news is I now have a new Camera and this one, a Sony 6300L is dust and waterproof and it's a compact. Everything about it is condensed except for the price $999!

But I found one with an open box, so they worked with me...$750

Bad news is I used the money I set aside for the torque converter :-((


So far this thing is vastly superior to the Cannon Rebel EOS I was shooting with. 24 M-pixel and a bunch of smart automatic features. Maybe it will improve the poor pictures I have taken for years.

It has a technique improvement setting. The way it works is to switch hands from yours to a professional photographer and you are supposed to get better pics!

Cool feature!

Funny, but the truth is not that far away.

I get my cameras from her mostly. She will buy one then in about six months, she'll see something a bit shinier, so I'll offer her something for the old one and just like that, you knuckleheads get a pic upgrade.

But not this time. SHe had nothing to sell. SHe has a Cannon D700 or D750, and some smaller compact thing like mine, but she wasn't wanting to negotiate, so I did this one myself!

So lets get this project going.

Today it was sleeting and snowing all day, but I said screw it and jumped in the thing after running my errands.

While I was waiting to begin, the truck suffered a catastrophic lower radiator hose failure. Apparently the clip fell out during a minor local quake and the hower hose came loose causing a catastrophic loss of dexicool on my driveway!

Unbelievable!

Stuff was stacking up pretty fast.

So far:

Air cleaner elbow
S&B filter and box
Cold side pipe
Upper radiator hose
Radiator overflow
Wiring harness from engine left side
right fender splash guard
turbo inlet bellows
Partial removal of lower rad hose
   Now working on the fan and shroud removal

It will be the impetus for a gasser truck replacement and Don will justify it by saying the pre rangers will finish it and it will be their first vehicle.

Except the pre rangers are chips off the old block and are better at blowing stuff up and tearing stuff apart and alas will sit the duramax until Christ’s return

But

I watched the Fleece Diesel vid about how to do this, and they had this cool whench that you actually smacked on like driving a spike in the ground, then through some mechanical linkage, it twisted the nut free...

It’s because the amount of money I payed for the site I think.  Don messaged and said I get three uses of the term.  However I think like in monopoly you can buy out of jail, so if Tex wants to hit that pay now button I am sure Don would let home back lol

So, Ken sent me off to YouTube land where I watched in horror the vids about how to replace a Duramax water pump

One word: HOLY CRAP!

That's a lot of business going on!

So just now I have ordered a 36mm 12 pt socket, a Lisle tool, and a big 3/4" breaker bar. (Mine is down at the farm, and effective yesterday, I have no transportation except for the Tiger.

Part of me fears that once apart this thing will never see the light of day. It will get rolled over to SqD’s former resting place and gather dust for years. It will be the impetus for a gasser truck replacement and Don will justify it by saying the pre rangers will finish it and it will be their first vehicle.

Except the pre rangers are chips off the old block and are better at blowing stuff up and tearing stuff apart and alas will sit the duramax until Christ’s return

Everyone done?

Can I post up some build stuff?

Pretty please?

OK gave it about 10 hours today. Knee being swollen and the brisk temps up until noon slowed me down, but from noon to around 1900, I had a clear field of running.

This is a pretty big job, really!

With the discussion about replacing the H2O pump, and my realizing I was short some critical toolage, I got those ordered this morning. Had to make it a two day delivery, but the Amazon peeps are saying I should see most of it tomorrow.

So, I just got right in and continued stripping things away to yield a clear view of the CP4A, and by day's end I had it!

Straight away, I pulled the IC pipes.

To do the job, get a big cushion to lay on while you spend some considerable time on your belly in the engine bay. THen pull the right wheel, and work on all of the bolts you can not get from the top from a seated position as far inside the wheel well as you can squeeze.

I had as a goal to have everything torn down and even the turbo removed.

Now the turbo is almost completely unbolted, lacking only the oil drain line. I can't figure it out, so I called it right there. I'll you-tube it in the morning and get the stocker out immediately. Then next is line removal, then it's CP3 time!

It isn't of course, just an optical conclusion!

But I may want to remove a couple blades to reduce the truck's weight to compensate for the upcoming 18K winch!

Should about balance out.

You see its physics

Spinnin things operate under new and exciting rules! One sez:
The mass multiplies when weight times the axial beverence quotation is applied

Like in helichoppers.

Law sez: Things that get to spinnin' get real heavy real fast. Then need to be, cause it seems that this spindly lookin' stick of aluminum, when applied to a pine tree will grenade the pine tree, and get you standin' at attention for about thirty minutes in front of your commander's desk

So ya, that fan can easily outweigh an eighteen K winch!

In some cases the blades on fans like this are not equally spaced.  Doing this can help reduce the noise that a fan blade will make.  The unequal spacing can disrupt the air movement and breaks up the frequency of the fan blade without having a large reduction in the volume of air being moved.

OK, fan blades are OK

And

This was not a good day

I thought this might just be a three day project, but now, I'm afraid to say it is going to be awhile

I'll explain why in a bit

But first let me say. There is a reason people charge $5,000 to install one of these CP3s in an LML. It is like the US Infantry fighting in hedgerow country following D-Day. You only make small advances. And every so-called next step requires two-three other actions to complets. Most every bolt is covered over by a bracket, or is out of sight, or just about impossible to even reach. You will be doing quite a bit of blind wrenching. I can't even imagine how much time I will spend reassembling this thing. I put another 8 hours in on it today, I'd say I have 22 hours in it so far and it's not all the way disassembled yet!

Last night it leaked another mess, so I started the morning with cleaning up

Post by: Flyin6 on April 18, 2018, 11:13:01 PM
So first up I needed to remove the turbo drain pipe

and this is how this project will go

First to gain access you need to remove the drivers up pipe.

TO get to the bolts at the manifold, you first need to move the big wiring harness
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 18, 2018, 11:14:39 PM
Then you need to gather the various wiring harnesses and zip tie them out of the way just to be able to get the tiniest of space to work in that cobweb mess in there
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 18, 2018, 11:21:59 PM
But then you will need to pull the transmission dip stick because the pipe is blocked by it. The bolt that secures it is completely out of sight. You can only feel it through the wheel well way up on top of the bell housing.

And that's when my day turned south.

The three bolts holding the up-pipe to the manifold are sitting right behind the fuel supply and return lines. Those are wrapped in heat wrap and rigid stainless steel. Two of the three bolts cannot be seen and are loosened by sense of touch only. Taking the inside, invisible bolt, it snapped off in the exhaust manifold.

That is a killer. Now the manifold has to come off to evaluate the extent of damage. Remember these exhaust bolts are a hardened stainless.Drilling it to use an easy out may be impossible, or machine shop only. Very likely I will need to just purchase another left manifold and wait the week for it to get here.
I'll look more into that later, as this easily has become a two week project and very, very hard and painful

I'd well consider if I needed a CP3 pump if I were you. If I knew I was facing this, it is doubtful I would have started such a project.

But after the bolt snapped off, I did manage to get the up pipe off
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 18, 2018, 11:23:22 PM
That allowed me to gain access to the turbo drain pipe and rather easily remove those two 13mm nuts, and pull the turbo

Then I went after fuel lines. If you go the way I went, having a lift pump, then all the added lines to/from the factory filter and even the filter and mount all get pulled off for good.
Here is where you will find a host of bolts which are covered by another line, or a bracket, or a sensor or something. Instead of using a ratchet, you will be using a dumb old wrench doing a flat at a time. And time that does eat up!
Title: Re: LML Duramax build Part 5
Post by: stlaser on April 18, 2018, 11:28:30 PM
Don, once you get that manifold off let’s talk before you spend money on another. Usually several different ways to get a bolt out without a machine shop. Also stainless can be drilled FYI, it needs to be drilled slow with lubricant & take your time. A carbide drill bit is even better if you have a way to center drill the bolt slightly first & have a way to hold the piece being drilled. Carbide bits will not take side loading and they will snap easily.

After taking all that crap off, I still can't freely lift the fuel lines, although both get modified. I finally managed to just unbolt the front half of the fat supply line. All the stuff removed is trash and will all be replaced by a short section of hose and a short steel line

Don, once you get that manifold off let’s talk before you spend money on another. Usually several different ways to get a bolt out without a machine shop. Also stainless can be drilled FYI, it needs to be drilled slow with lubricant & take your time. A carbide drill bit is even better if you have a way to center drill the bolt slightly first & have a way to hold the piece being drilled. Carbide bits will not take side loading and they will snap easily.
But, except for the Triumph, I no longer have a ride. I'll evaluate it when I pull it. But options are limited right now

Uber?

That would have been the worst part

No work on it today

Pushed the knee too far last two days, taking the day off.

Called to order a new Pro-Fab passenger manifold, however, just found out they now have a new (different) design. Waiting on a call back. It will be next week sometime when I drive again...
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 20, 2018, 10:26:16 AM
OK, so I just spoke with the folks at Pro-Fab about the snapped off bolt in my manifold

Rick has changed the design of the manifolds, so if I ordered a new driver's side manifold, I'd have to either send him my up-pipe to get modified, or buy a new up-pipe, and then I'd essentially own some hybrid set that would be hard to service in the future, and I just demonstrated that service is indeed a possibility in my future.

So I just ordered a new set of manifolds and up-pipes. THey should be in the mail early next week, so true to my word, it is going to be two full weeks to get this job done!

That hurt the pocketbook, but Rick did offer to buy back my old manifolds and up-pipes. He could refurbish and resale, and offered me a fair price for mine, so all in all, I do not consider this to be such a bad deal. In the end I'll be out some $500 more ish, but that's life when you get to messing with these very expensive diesel trucks.

In the mean time, I'll get the rest of the job done and prepped for final reasembly.

The biggest problem imo is the grade of the stainless. Hardware store stainless is way to soft (similar to grade 2-3). I think ARP carries the good stuff (like 17-8 iirc), but still degrades with heat (loses rigidity, stretches),  isn't as flexible, and all of them are capable of gauling.
...and use copper anti-seize for high heat. The silver works, but not as well.
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 20, 2018, 11:08:24 PM
Copy on the stainless thing
FYI, all the fasteners were coated with copper anti seize when assembled. Apparently the galling still took place. Almost every fastener had some galling on extraction. THe one bad one resisted the many spray-downs with the penetrating oil I use on stainless hardware and snapped off.

So now that I purchased a whole new cast manifold and up set, the 2" or are they 2 1/8"...?? Anyway, the first thing I did today was to pull off the remaining up-pipe

BTW, if anyone wants to purchase the manifolds and up-pipes, you can have them for $400. That is what I was offered by Rick to ship them back. You would have to extract the broken off bolt, but other than that, they look to be in good condition.

I'm getting serious with getting clearance to move around. The bolt below the second from the rear cylinder was directly behind the shock tower, so I drilled a 2" hole in to to get better access. Even with the hole it was tricky getting that bolt out

I used a lot of engine assembly lube when putting this thing back together.

The main fuel lines went back into the valley with the pictured shorter 90 degree piece replacing all that other business.

So you think removing the water pump is almost done and just a quick couple of bolts???

Why were you thinkin' that

This is a Duramax where the reasonable guy was not invited and engineers were left to have their way with things. Nossir, you still have to work with bolts which are masked by steel lines and two very sinister aft facing water neck nuts which I could only get to with a 30" combination of extensions and a 13mm deep well.

I really have no clue about how to get that inside nut reinstalled!

Oh and you first have to remove some guard and a wiring bundle loom before getting to any of that.

Here's what you face before starting:

I needed a small victory, so I just removed the small ball mount for the cable bundle to the fan clutch and transfered it to the new pump. That was the last press of the "That was easy button" I got during the H2O replacement ordeal

Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 22, 2018, 02:59:57 PM
Now fitting the H2O pump back into place is not a slam dunk either. You must carefully align the aft facing strud into their opposing holes in the water stand pipe, all the while trying to align the main housing into the big hole in the block, while fighting the natural tendency for the thing to never fit in the first place.

IT took me a half dozen attempts, but just like the stubborn CP3 pump, on one such attempt it just slipped in like it was made to fit there. I bolted that sucker up in a fast second before fate would have the chance to change things up on me.

Post by: Flyin6 on April 22, 2018, 03:16:00 PM
I went to make the final electrical connection to the CP3 pump only to discover the harness it too short!

So I'll have to cut and lengthen the harness to complete the CP3 installation, but other than that, that big job is done minus reassembly.

Now reassembly is going to be a sorted affair. I could drop in the new turbo and get right on it, however, I really first need the up pipes, which aren't here, and haven't even been shipped yet. So, I'll get in and remove the remaining manifold, do all the turbo prep work, and just get ready, but basically be in a pause until I get the parts.

In the meantime, and in the spirit of my usual oil changes, I'll pull/paint/rotate the tires, pull/paint the shocks which picked up a bit of corrosion, and wash/degrease/and paint the chassis like I normally would following a Kentucky winter (6" snowfall/8" salt application)

I already started pulling the shocks and wheels...

Don. Refresh my memory on why you decided to replace the pump?

Also Ken may chime in here but I’ve heard that the O ring for the tube on the pump has created problems for some as it can roll out of position as you are reinserting it. I would have told you to make sure and lube the inner surface of the O ring and the mating surface of the pipe but since they are already back together.....I may get reprimanded for failing to tell you sooner. 

Also sir, I see your safety snap ring is not correctly installed on your fumoto valve. I would think a helo pilot would like to have safety retention devices installed.  With all the stuff you run over you don’t need the valve to inadvertently get opened.

Other than that it’s looking like you are making good progress. 

CM sir.

We also silicone the steel gasket on the pipe coming out of the back, and never reuse the old one... I mention this because I didn't see that part of the installation above.

We also silicone the steel gasket on the pipe coming out of the back, and never reuse the old one... I mention this because I didn't see that part of the installation above.

On the Fumoto valve, I'll look at it, it has been that way since 2011, so at least we know that an improper installation will still work even when the truck has literally been off road in primitive conditions literally hundreds of times

On the O ring on the top. I didn't have any new ones, so I reused the old one. I sprayed it with spray adhesive with it sitting on a piece of cardboard, then using needlenose placed it into the groove, then pushed it into place with a flat tip screwdriver.

On the gasket that is attached to the standpipe on the rear outlet of the H2O pump, I did reuse the original. It was like stuck to the stand pipe and looked, well, new. I only wiped it down prior to finagling the pump into place. The gasket is captured immediately because of the two studs. The top O ring wasn't going anywhere because of the adhesive. I watched for any movement as I pushed down and rolled the water pipe onto the surface. It fell into good alignment, then I reattached the bolts.

The new Delco water pump came with no gaskets, no O rings, nada. I would have thought the thing would at least have had the O-rings and have studs installed, but it seems even ACDelco has gone cheap on us.

Having heard what Ken says here, I am a bit nervous now, because the thought of a teardown after reassembly is not something I would like to do again, but I am at a bit of a loss. I called around and the lower hose and the AC Delco pump were both special order items and a few days out. Honestly, I think one could take enough precautions that he would not see the use of his trucks for a month or more. Using the risk/reward matrix way of thinking, this thing reaches the point where I feel I need to reassemble it to see where I am. With some good fortune, I will be done. If I am wrong, well, I would be waiting anyway.

But it's not that two dimensional really. You see you start off with one condition understood, But then along the way things happen. Like the snapped off bolt on day three. If I would have known that was going to happen, I would have ordered the pump and hose from the O'Reillys and that would have been that. The time it would take to come in would have been covered. But starting off, I had no expectation anything like that would happen.

And then there's the gallery aspect. People will give you all manner of advice...AFTER the fact. It has happened a couple of times on this thread alone. (After I took the advice and ordered the ACDelco pump, I find out that there are several grades, and I didn't even get the OEM quality...!)

Not to take a shot at any of you, because I know you all care, but often it seems, the "You should have used the one with the purple stripe" comment comes the day after you did it, and then buried that work with a bunch of other work. That sort of advice to me is not useful, except to give me a place to go if a problem arises. So if I have a H2O leak, now at least I have somewhere to start looking, but other than that, the work is already done and the parts I didn't know about aren't available here quickly, and are likely three days away, and I don't have a way to get them anyway if its raining.

So what's done is done. Although you all are free to offer whatever advice you wish to offer, and I appreciate it, for the reasons I stated, which are clear to me, I can't follow along.

I said it before...Timing! Timing is important...

Don. Refresh my memory on why you decided to replace the pump?

Also Ken may chime in here but I’ve heard that the O ring for the tube on the pump has created problems for some as it can roll out of position as you are reinserting it. I would have told you to make sure and lube the inner surface of the O ring and the mating surface of the pipe but since they are already back together.....I may get reprimanded for failing to tell you sooner. 

Also sir, I see your safety snap ring is not correctly installed on your fumoto valve. I would think a helo pilot would like to have safety retention devices installed.  With all the stuff you run over you don’t need the valve to inadvertently get opened.

Other than that it’s looking like you are making good progress. 

CM sir.

I believe, after talking with some mechanics at a local diesel performance shop, and two other diesel performance shops that the CP4.2 is unreliable. I believe it has the potential of failing and causing damage which would exceed my monetary ability to repair it.
This was an act of insurance to gurantee as much as is possible a lifetime of service from this truck. With the costs increasing into the stratosphere for new vehicles, and the fact that a several thousand dollars of that cost are for pollution controls which actually contribute to the failure of the powerplant, I will not be purchasing a new diesel again, I think.

So this truck will likely serve me the rest of my natural life in some diminished capacity and with it being paid for, it is a high payoff vehicle to me.

The VVT turbo is a problem with these trucks as well. Oil suction into the intake and other factors seem to contribute to the failure of these things. Going old schol seems to be the correct answer to me. I'd rather go away from technology than to try and embrace it. Thinking about it, everything that has been electronically enhanced or over engineered is what drives the cost up, and also adds to the failure rate of these tech heavy trucks.

For me: NO THANK YOU. A CP3 pump, feeding a well designed old school turbo that is now easy to remove is the answer. I will have nearly double the Horsepower of a stock truck, probably 20% better economy (with 4.56 gears) and greater reliability.

I checked before doing this. My cost here in the tuck was a tad over $5,000 to replace the pump. If it failed, and caused the failure of the injectors (Common) add another $7K to that figure!!!

No-

Same with Ken. You two are good hearted and well intentioned.

I am just making a "Point of order" addressing the timing of some of the advice.

Just because it didn't help me, it may (will) still help others who will use this thread as a reference when they do their conversion

Tex, take a look at the D-Max thread where I remove the EGR. There is almost always someone logged on there, no doubt, learning how to d it. Same-same here

That hose is just for draining, and does not retain any engine lube. That is the job of the deeply detented valve lever.
The only reason I keep that covered is that I was getting a higher silica reading from some oil analysis reports which they/I traced to a bit of dirt getting into the sample from the draining process.

A vacuum cap seems smarter, think I'll switch!

Yea, you're fired

For giving me post action advice, and for inferrin' and stirrin' up stuff!

Repentance needs to be your way, my son...

So to earn your conditional re-hiring (Man I like firing people!) your question is:

Kenneth, do you think I can get away with the reuse of the factory gasket on the oil cooler supply pie? It seems to be a thick rubber gasket with a raised O ring seal about the center. It looked like new and was stuck to the oil cooler pipe...

And for now on, you people start keeping a track of how many times you get fired for these heinous crimes! Remind me the next time you do something dumb, so I'll know how much to fire you that time...OK?

Yea, can appreciate that setiment. But the Powerstrokes have faulty fuel pumps as well, and the Dodges suffer from their own particuliar issues. Nobody gets to walk for free.

Having thought it over, try and find a used one for cheap. THen address the issues you know of through the experience of others and address those like i am doing here. Then afterward, you have a 700,000 mile truck. So you drive an exceassive 30K a year, you have over 23 years of use. So you drive it for 10 years as your primary transportation, then use it only to pull the camper, get heavy things and once in awhile with the kids. Send it off to college with a kid or two, then bring it home for the rest of your life.

That is what we are talking about with these trucks, industrial/commercial equipment. I'd spend money (As I have) spraying preservative and rust preventer was/cosmoline/grease/whatever into the body cavities, so that the body has a chance of lasting as long as the mechanical portion of the truck will.

I wouldn't buy these trucks with my sights on trading once every 6-7 years. Because you haven't yet begun to experience the benefits of operating a paid off vehicle. Nossir, in 8-10 years buy yourself a little diesel colorado or Jeep and drive that for fun, but knowing the diesel 3/4-1 ton always has your back.

We all have the same kind of luck (Murphy). I would probably order a new cooler gasket and orings for the top tube.

Well, Ken, after considering your advice and weighing your experience, I decided to pull the H2O pump back off and gasket it up.

But later on in the day, I was poking around on the exhaust manifold and just happened to notice the water neck to oil cooler gasket laying on the garage floor next to a jack stand...Yea.

Had I not decided to pull that pump and just do what you advised, I would have been pulling all that crap back off the front of the motor anyway.

So good call all around!

Today was just tough!

I decided to pull the drivers side manifold off the truck to get ready for the new manifolds which got shipped today.

I think I worked most of the time I had to spend on the project just getting the bolts off that manifold. It is just one miserable job, no fun at all.

Look at what you have to work around...Notice that you can't really even see the thing, let alone the bolts on the underside:
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 23, 2018, 09:58:23 PM
So just like on the other side, I had to pull the shock, then drill a 1.25" hole in the shock tower to have any hope of getting a socket onto one of the bolts. Then I had to pull part of the steering column to gain some access to the front. Then taking it off, I almost had to pull the block adapter and oil lines for the Amsoil bypass oil filter assembly, but because everything is loose up on top, I was able to yank, turn, wiggle, and everything else imaginable to finally get the manifold out.

I just hate this part of the job!

At one point I had to create this tool, by taking an old hex socket, cutting off an eight mm allen wrench and hammering it tinto the socket. THere is no other way to get to the bolt under #3 cylinder back, even when using the hole I created in the shock tower.

And with the manifold loose, you can see there is no way it is going forward or up with the steering shaft connected.

It seems that to do this job (if you have to pull a manifold), you are going to touch nearly everything on the front end of the truck.
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 23, 2018, 10:05:34 PM
And then just to prove that nothing is fair, I went to pull the frozen stud out and it came out fairly easy with no damage to the manifold!

So, if anyone wants some LML Pro-Fab High-flow manifolds and 2" up-pipes, I now have them, ready to ship $400.

That's what I am getting for them  in trade, so before I send them back, they will be available.

I was thinking (wondering) the same thing

Then I realized, last time I removed FACTORY log manifolds, where one can actually see the bolts one has to remove

But then, I only installed the Pro-Fab manifolds. Installation is easier. You place the fastener onto the hex drive, fish until it finds a hole then turn it in until you're happy. Find it one more time for torqueing or final tightening, that's it!

I have an inbound on the manifolds, will arrive tomorrow. So today, I'll remove the H2O pump pending arrival of the new gaskets (Thanks Ken) then pull the rear shocks to get cleaned/painted, pull some wheels for painting, and maybe do some more turbo install prep work. I might even pull that pot-metal, rusty read diff cover Shawn sent me and paint it as well!

Then there are a few things like the relocation of a water line and blocking off of same, a pedestal and some small stuff like that which I can get prepped up.

But coincidentally I am taking this time to also do the spring recovery/summer prep work. I'll go over and touch up any rust spot on the frame/chassis I see. THen do a complete Chassis lube.

I degreased the front suspension area. A boot from an axle shaft had torn and centrifuged grease everywhere, then there was impacted mud. I got most of that out of there during the past couple days, so now I'll repaint and lay down a layer of parriffin wax and that will bring me up to spec.

I am treating this thing like an aircraft. I watched the mechs tear down the Chinooks frequently to hunt for corrosion after guys like me would land then in ocean swells (Unintentionally) in like sea state seven to try and pikd up seal teams bobbin' out there like a cork, 50 miles from shore. Ocean water and 160th Chinooks are well known to each other and at nearing $100 mil a plane, they require lotza care. That's because they intend to use them for a long time

I always chuckled at that. THese politicians buy these spec-ops aircraft thinking they are going to keep them flying for 20 years. Then a Commander comes on board who wants to leave command with no losses (aircraft or peeps). Then they assign a mission to a guy like me...And what do I do? Land then in salt water oceans, get 7.62mm holes poked in em, chop pine trees up with em, run em out of oil, but try and fly then 250 more miles, and other things like that.

But my C-Max is not like that.
I am not:
1. Driving into any deep lekes to pick up anyone
2. Intentionally drivin' into any gunfight
3. Intentionally driving into or over any tree bigger N' say 3"
4. trying to park on any hill sides on my back wheels only

Nope, none of that!

But

I still have to:

1. Drive near malls with deed, very deep mulch beds!
2. Drive in hippie infested traffic where everyone is in some small kolean kar and in a race to get somewhere
3. Drive in 1/2" snow covered with 3/4" of salt
4. Drive into gas stations where a bunch of mexicans are throwing trash out of their car that I just told to go back and pick up (Possible gun fight there)
5. Drive in this slippery morass they call mud to get to one of the prudiest places on earth to work until I pull a muscle.
6. Maintain some form of respectability when attendin' church or other civic places (So I don't get immediately as a hick)
...And other things like that, and for those reasons, the added corrosion prevention measures, N' kleanin'

Getting there, looks good.

I did order the PPE setup for mine today and a new turbo wheel. Think I have about $5k in parts to go on the LBZ so I need to get that thread going again!

I see many retailers are using that same tuner you listed above.

You don't remember, but when I first installed that cover, I asked you what was the best way, and you told me to use studs

So I purchased a piece of threaded rod and cut out a bunch of studs from it, and the rest is history...

Great. Maybe a little $$ for the sight and a better running truck for me. Only issue I see is all this is leading to a trans build,,,,,,,,,,,,,,

From what I've read the LML trans is nothing like the old version of the Allison.  It's held some pretty hefty HP with just a TC change.

Correct.
Both Motor Ops and Diesel ops tell me they run trucks making 800 HP with a totally stock transmission, albeit with programming to increase line pressures.
One guy who I talked to in depth said he finally pulled the converter and changed it and ran the truck some more making something between 700-800HP. He finally couldn't stand it any longer, and pulled and did a whole transmission. They noted on teardown that some of the clutches were showing signs of excessive heat, BUT the trans did not die.

From LML forward is really a totally different animal. LMM and earlier, you mod and the trans will fail. LML and later it most likely will hold. I don't pull, race of act stupid. I'll bet my stock trans with a converter...I will add a triple clutch converter, but I'll bet my combo is viable in six more years.

A bead of silicone and some fresh hardware and it was reinstalled along with a gallon of GL5

Post by: Flyin6 on April 26, 2018, 09:02:04 AM
...And then, all the trouble started. It was one something when I started to install that pump.

It is a very difficult alignment one needs to achieve to get it to fit. I kept trying, then would take it out, examine it, then try again and so forth

I finally determined a casting flash on this high quality ACDelco was reducing clearance to nill, so I filed it down some but still I couldn't get it to fit.

You see, at the exact spot where the circumference of the body of the thing is set to engage, so are the two studs on the water neck. If you get one, the other may (will) be off and out of alignment.

Now you are doing all this from above in a very awkward position which makes holding the thing up against gravity and also seeing the stud alignment a very trick prospect.

So in out it went. I smashed my thumb and tore skin off a finger, blood spots everywhere to prove it, and then I remember the boys coming home. They get off the bus at 1525! So let's say it is now start plus 2.5 hours and I am no further ahead than the moment I started.

So I jammed it in there again, but this time I took one of the wife's compact mirrors and looked at what was going on. THere is this small stud at about the seven o'clock position which must also be engage at the same time of exact alignment and studs finding two holes on mr. floppy tube.

Getting this in alignment is the celestial equivalent of all the planets aligning at once with the sun, and throw in a couple of moons to boot.

But with that knowledge in hand I made my move and having grown another six fingered hand, I shoved that bad boy home and finally, finally got the pump in around 1600.

Been that way since the beginning

It's too long to fit in and leave any space to work around the front.

Neighbors here just love things like trailers, garage doors open, and torn down trucks protruding into their view.

I was doing OK, but a tornado came by two years ago and took out a few trees that once shrouded me.

I don’t recall how the tool works exactly, but remove it from the transmission access panel before you try to start the thing. Probably silly even mentioning it, but I feel that would be a nightmare.

I did a water pump on our LB7 we had in 2009, only reason I am vaguely familiar with the tool that stops everything from spinning, and it is for some reason in my truck tool bag still.

Well, yes and no Nate... He already moved the A/C compressor out of the way, so we know the lines are flexible in spots, so the condenser should be able to be moved a bit too to aid in working room.  The condenser is considerably smaller than the radiator and intercooler, and is the front-most item in the stack, so that would gain him 4-5" fore/aft of working room for wiggling the pump in and give him some line of sight on the sides.

Here's a pic of the front end of mine torn apart 2 years ago. I was able to remove the core support without disconnecting any of the A/C lines, thats how much play it has.

Caveat here -- mine is an '06, Don's is an '11, so I don't know what all has changed...

On the LML's the radiator is actually welded to the frame, and the other coolers are welded to it, and soldered and glued to the front facia and the fenders.

Very different, these newer trucks!

And if anyone is interested, I'm tired of the brooklyn bridge, so I think I'm gonna sell it.

SO today was the one I was dreading but I have to say, it was not too bad.

I started with coating everything else I had with the copper spray and even coated one manifold as an experiment to see how well it holds up and if it stays there at all. Like zinc, the self sacrificing metal, just to see

Post by: Flyin6 on April 26, 2018, 10:37:24 PM
I reinstalled the transmission dip stick and some things on the sides of the block, but just like that, it was time to drop the turbo onto that pedestal.

There are four studs that it sits on, three of which are easy to get to. The forth is a bot of a problem, but I found that by wiggling in a magnet holding the nut, then placing it onto the stud, I could use a screwdriver to spin the nut a flat at a time, and that got it done.

JR, the passenger up pipe is already too close, no extra room for any wrap. Only the drivers side has clearance, and woe be to you should it bind making installation more difficult that the monster it already is going to be with a stock turbo...

Yea, went quiet for a couple days, because of being down under at the farm.
And
Having to deal with what went on there...
Started out as a normal weekend, doing Sat-Sun there because of great weather and moderate temps.
We were killing it with getting things done, then mom invited our youngest daughter down for Sunday afternoon.
That was OK, right up to the point where the youngest pre-Ranger was giving her instruction on how to ride his dirt bike a Honda 80cc thing.
It was a repeat of my big wheelie that ended in disaster. She took off wide open and crashed.
She broke her leg in two places and broke her elbow as well. Then while she is literally screaming, a lot of screaming, Kat tries to fire up her Lexus to drive her to the hospital. From where we are, it takes 45 min to get an ambulance on a good day, and you are looking at a 40 min drive to Lexington, or 1.2 hrs up to Florence. So, yea, that vehicle was dead, so kat hauled her off in the GJ and left us alone. We didn't get out of there until 0100 and the daughters car is still broken down, and as we all so well know, m truck is still disassembled!

But despite Kat pulling an all-nighter at the hospital and my having to do domestic stuff, I did get some wrench time in

First up I changed the oil. I didn't realize the Fleece turbo was not H2O cooled, or I would have purchased straight synthetic oil to reducing coking. What I did do is add one gallon of synthetic to two gallons so the mobil diesel oil to get me going.

I also ditched the uber expensive Amsoil bypass filter. I am using two conventional Wix oil filters instead

Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 30, 2018, 09:45:02 PM
The hot side intercooler pipe had been rattling against the brake accumulator housing, so I wrapped it with a rubber sheet and taped over that with electrical tape. I hope it all holds!

Then I installed a new silicone reducer boot onto the turbo.

The turbo outlet to pipe alignment is not perfect so I had to loosen all the compressor bolts to attempt to rotate the housing for a better angle. Now, this thing is fighting me with every single thing I do, and now the compressor housing will not rotate! So did they glue it on??? Or is it just this demon of hard work messing with me some more?
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on April 30, 2018, 09:48:24 PM
So I went on to install that front cover vent I broke and repaired earlier. And would you know it, that thing fought me for nearly an hour. One little bolt, and one hose clamp and I just beat my hands against that thing for what seemed like forever. By then I was looking at 1930 and time to throw in the towel on something like two+ full weeks of work. Man this is one big/difficult project!

The old boot held up well, but shows some signs of oil ingestion.

Thanks everyone.

Momma stayed the night with her again, then went to work. I don't expect to see Kat home tonight for more than a clothes change. When someone in the family gets feeling bad enough to be hospitalized, she stays with them until they come out.
Hed dad was taken off to the hospital when she was nine, because he wasn't feeling so well. He never came back. It made an indelible mark on her. She will not leave anyone, even friends, alone.

Allie is the (not so) baby girl. Currently awaiting news...

On the Triumph in a few to go see her. Will follow up with some work on the truck in the afternoon.

Next, the hot side pipe is reinstalled with additional padding.

Something interesting happened. Either I couldn't find all the bolts to the turbo compressor or the darned thing is glued together, because I was unable to loosen the bolts and rotate the housing. So I have about a one to two degree misalignment with the pipe. Not bad enough to be of a major concern, but not right.

This thing just fights you every inch of the way. It seems like every single task you attempt, turns into some ordeal. You find yourself just dealing with one issue after another. This has not been a simple bolt on at all. It has been a manifold task that challenges one's will to continue.

In a few words, it has not been fun at all!
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on May 01, 2018, 11:36:20 PM
Then the cold side pipe was reconnected. It was not difficult at all. I suspect something bad is about to happen. Nothing just goes back on. Maybe it will explode, taking the truck and me out when I hit boost the first time! YIKES!

The the shocks, after I lubed the suspension and steering, and some brand new bolts and lock nuts which I left loose on the lower mount to prevent any binding. I use a ton of grease on those mounts, bushings, and bolts. I hope to stave off corrosion for a couple years.

Oh, and I have been adding a dab of grease to all the hardware, the ground strpal, the cannon plugs, and all electrical connections and even the O-Ring seals.
Title: Re: LML Duramax build Part 5
Post by: Flyin6 on May 01, 2018, 11:41:01 PM

No, those 37's look small. The truck needs 40's or even 42's to "Look" right. However, it drives really well and corners safely at some pretty good speed with the 37's pumped up to 40 psi

Well, this is day number "Who knows what, I am lost in this never ending process!

While I was fresh, I tackled the radiator fan and shroud

It is a chore, but easier than the manifolds. You need to see how everything lines up first, then just sort of wiggle and coax the assembly, which is heavy, down into place at the same time. THe trick is holding everything together during the "positioning" phase.
Title: Re: LML Duramax build Part 5

I reattached the battery, topped up the radiator, and attempted a restart. It took several attempts, likely due to no fuel being in the pump or any of the new lines. But then it rumbled to life. I only let it run a second or five because I was still on the old tune

So it was now time to load the new tune.

I called Motor Ops in Ontario and was lucky enough to get Dahnyl (pronounced: Daniel) Charles. He did a remote session with me and transferred the tune to the autocal and made some of his adjustments and updates.

He stayed with me all the way through a full flash of the truck's ECM. What a helpful guy! I have talked to a host of people up there and every single one of them is just great to work with.

The tune loaded effortlessly and when I touched the starter, the engine started immediately.

It sounds different. None of that annoying LML vvt crap. It just has a big wholesome full V8 sound. I mean it really sounds great.

I allowed it to run for maybe 10 minutes while I checked for leaks. Amazingly, I had none at all!

It just runs, well idles, great.

No test drive as the sun, she was ah-settin' so I'll have to wait for some bad weather to give it the full test. Dahnyl did say he put in a tune that typically makes 600-650 HP, so my estimate of 625 should be right on the mark. Plus, I have those mo-betterer exhaust manifolds and up-pipes which have made an additional 34 HP all by themselves.

He also agreed that my stock transmission should hold just fine.

Then I reattached the wheel well liners and the radiator cover using new plastic clips. The ones in the plastic bag are the closest to the factory ones.

Wheel wells slid right in. I also coated all the rubbing areas and all the hardware with the clear grease. Overall all this anti-corrosion measures I have takes have produced a rust free vehicle despite the hostile winter environments here in the rust belt.

Post by: Flyin6 on May 03, 2018, 09:17:10 PM
Well, the test drive was interesting to say the least

First of all, I mounted the steering shaft (wheel) 180 degrees out of phase! How funny is that. Can't see anything from under the hood, and a shaft reconnected is a job complete, I always say
Oh and when your steering wheel is upside down, the blinkers do not cancel after a turn!

Second, the turbo makes the truck sound somewhat like a powerstroke. You know that particular sound they make??? Well my D-Max sounds almost like that!

I got 76 MPG today over 2,000 miles of driving. Not bad, and that may not be true!

The EGT's are lower, for sure. I never saw four digits even once when I saw the boost gage sitting on 33psi!

There is no turbo lag at all. You step on the throttle and it's there

The transmission is still learning, so I am no where near how the thing used to shift.

The speedo is W A Y off. 60 mph indicated is actually 47 on the GPS
On that count I called Dahnyl, who looked over the tune he sent me and discovered an error in the correction factor, which he corrected. He already sent me a new tune that, as of this writing, I am unable to transfer from the desktop to the Autocal. I'll call him and fix that tomorrow.

I have an appointment for an alignment tomorrow. They say they can correct the upside down steering wheel without having to remove and reinstall the steering shaft, which is deeply buried in all that stuff on the drivers side of the motor.

The sound is just so different. Not Duramax at all. Maybe a cross between a 6.5 detroit diesel from the 90's and a souped up 7.3 power stroke ford...definitely different.

I will simply not accept this, age has nothing to do with it, cost sure but when all said and done you just dumped $5k into that truck and I won’t let you cry poverty to me afterwords. 

Long ago I made a deal with a friend that if someone or anyone says “do a burn out”, “spin your tires”. I do it.   Being a little kid and watching that was some of my favorite memories. Plus in you case it will royally piss of the neighbors

Don, don't let them correct the wheel by adjusting. On top of that, it would be good to know which way it came off, because there's a clockspring for the airbag under the steering wheel (think recoil spring on a lawnmower). It is only meant to turn, and wind/unwind a certain amount. If I was paying attention, I would've told you to strap the wheel with the seatbelt before removing the shaft. hindsight and all that

Don, don't let them correct the wheel by adjusting. On top of that, it would be good to know which way it came off, because there's a clockspring for the airbag under the steering wheel (think recoil spring on a lawnmower). It is only meant to turn, and wind/unwind a certain amount. If I was paying attention, I would've told you to strap the wheel with the seatbelt before removing the shaft. hindsight and all that
Ken now you are gonna get him fired up about giving him information late or after he had already done it.

Yep, here we are in hindsightville again!

Welp, why should I not have them adjust it out?

Remember I have those really big and very, very deep engaging tie rod/baseball bat things on the steering.

I have an appointment in like 1.5 hours, I have no time (or will) to tear into that thing again.

And I do know all about the clockspring, broke one in my Tundra when I did the SAS.

Having said that, I have no clue about which direction the wheel flopped to or which direction I twisted it to when I reconnected.

This is either going to work, or break the clockspring. I think it is a done deal, and water over the dam at this point.

It's a through bolt JR, 13mm thing. The shaft is hard then bolted after the U-Joint to the sector shaft of the steering box. After removing the top bolt, I pushed the extendable section extending from the steering column up and back into the steering column. At that point gravity took over.
Following that a few days later, when I reconnected it, I rotated the shaft another half to rull turn, possibly 1.5 turns. It could be 50% off, 1 full turn or even 2 full turns. Enough to break the clock spring???
We will find out in a few hours!
Man this is frustrating.

The good news is the thing runs great.
It no longer has the problematic CP4.2 pump.
It no longer has the troublesome 9th injector harness assembly
It does have a ton more power
It now has a much more easily serviceable turbo
It has at least 50% fewer electrical connections under the hood (Read: Simpler) than before.
It has a lot less junk under the hood than before.
It no longer has a convoluted cooling system which was overly complicated by having to cool an EGR system and a turbo.
Now all that not used cooling capacity is just a big reserve for those really hot days that I never had before.

...And, working with Chris this morning at MotorOps in Ontario, we reflashed the PCM and now have the speedo within 2 MPH at 50MPH. No time just yet to test it at 70.

And

Allow me to put in a plug for these Canadians. THe guys at MotorOps have just been one class act. I have dealt with them now since October, last year, and they have not failed me once, nor have they failed to deliver on a promise. They do what they say they are going to do, and write some spectacular tunes for these Duramax engines.

Talking to them this morning, I think we are going to offer their tuning through this web site. I may be a little preemptive in stating that, but we are talking about it. I/we demand honesty, truthfulness, a good product and a reputable company who share our beliefs. I think the Motor Ops folks are like that. Just like the Diesel Ops folks, I would like them associated with us, so standby for a standby.

On a chebbie, to adjust it out they have to use the tie rods....in other words, you'll lose a half turn in one direction, and rub tires the other direction.

This tune was something leas than $200, like maybe around $150ish???

I purchased the EFI autocal and license from them back in October of last year. Once they have your base file, they can upgrade based on hundreds of known factors/mods.

THis is EFI Live, the real deal with the DSP5 switch and 5 programs.

Post by: Flyin6 on May 04, 2018, 07:19:39 PM
OK, today was a success. I told them to drop the steering shaft and align the steering wheel that way, as per Ken's guidance.

So when they placed the steering wheel in the centered position and checked the alignment, everything was within spec, although some parameters were flirting with the limits. So I had them bring it in to nominal settings.

Driving the truck was a pure pleasure. No tire vibration, the steering is about dead neutral. No wandering or darting about ofr seeking the up or downside of the crown. It's right

And the tune is now within 3 MPH from 50 MPH through 75 MPH indicated speed.

The power is just everywhere, although it now sounds like a low rpm powerstroke. And I noticed at least one MPG better already. I did some highway cruising at 70 MPH along with some idling at McDonalds and waiting at traffic lights. Make it a 40 mile loop and at the end I was sitting at 18.0 MPG. That means that country road driving will probably show 3 MPG better for a theoretical 21.0 MPG on the backroads.

So far this is turning out to be a great combination for the LML.

But,

For some reason and for the first time, I got a caution light for the stabilitrak! Never saw that before. Heck, I didn't even think I had that!

^^^^Thanks Kenneth

So, took it on another loop today. I mostly drove 60-62 MPH, but got slowed down and stopped for awhile in a traffic jam.

Believe it or not, when I pulled into the driveway to park, it was registering 20.8 MPG!

It has never shown me numbers like that before. This turbo, supported by a CP3 and this Motor Ops tune is great, really is. The truck just feels lighter and more responsive than it ever has before.

With the promise of the torque converter shaving a full second off the zero to sixty and increased mileage, my almost 9,000 lb truck has not yet reached its potential.

So far this is showing itself to be one great modification.

So to report on the assemblage:

Fuel mileage has improved everywhere

I towed three times, light, then maybe 4K then maybe 7K-8K

Mileage was 16.7, 16.3, and 15.3 MPG on each sortie. Speed was a factor. Towing pretty light on a country road I was mid 17's, then had to do a loop at 70 ish and it dropped to 16.3 MPG

I do not like the sound of the thing now. It sounds like a powerstroke, and those things always sound broken to me. The turbo change really made a substantial difference and it is much louder now. I have no reason for that, but it is. So my plan for that is to find a larger muffler and install that in the 4" system replacing the MBRP muffla' that I run now.

But the truck decided to fight me some. I hooked the trailer up to go over and pick up my soffit materials. I get there and one of the tires is cut completely in half! I really couldn't believe it! Never heard it pop, but did notice a strange whining sound on the highway.

But with my helicopter pilut ears, I couldn't hear a nearby atom bomb explosion anyway!

Then I get to my destination and I notice the lift pump is not making any sound

Yea, lift pump again! That's what the third or fourth time that Air Dog lift pump has failed. I put two motors in it over the years, but I think I am done with the AD product.

I do recall the warning from Fleece that this modified CP3 pump requires a lift pump with a 2 micron filter, so I'm parked again, awaiting another costly fix.

Guess i am in the market for a Fass or similar lift pump! Say good bye to extra cash I thought I had!

I have replaced the motor in that thing twice already! Twice in less than 80,000 miles.

I have been doing my homework. Air Dog uses Chinese motors! Boom! Should have known. Replaced the first one then had another issue, and got a second motor which they did not warranty. Like $250 if I recall.
But the big issue to me is that these Air Dog units will not go the long haul (Read: Unreliable)
I can't have that in my truck. THat's the reason I just forked over five grand for a CP3 and new turbo. Reliability and knowing the thing will be around for the long haul.
Nothing I have ever seen in Air Dog has ever shown me it is reliable. Thinking about it, way back in like 2012, I had an issue with the thing leaking out of a fitting, then if I recall, a cracked housing.
Even if I have that wrong, this pump failure rate is such that in an aviation application it would never get certified.

Contrarily, I see testimonies of Fass systems going 750K-1,000,000 miles trouble free. 97% American made (Not just assembled) with an American motor.

Decision is made, I am switching to a fass and making the Airdog a target for my 7.62 next weekend...I'll post pics.

I just talked to some folks about the available fuel pump/filter systems.

I have a strong consensus that Fass is by far the best. One retailer I spoke with earlier today said they were seeing returns and unreliability on the AirDog systems, but almost no warranty returns on the FASS systems

One thing I learned is that with FASS, the number on the unit represents actual fuel flow numbers. For example, the FASS 95 unit actually pumps 95 gallons an hour at 10 psi.

However with respect to the AirDog system, the number associated with the pump is just a part number. For example my unreliable AD-165 actually does not even flow 95 GPH! I consider that deceptive which is in my book dishonest. I witnessed a test where the AD-165 was tested against the FASS 95 system at 10psi. THe FASS 95 out flowed the AD-165 by a few GPH!

So I will be purchasing the FASS 165 which will support up to 900 HP. That easily covers the 620HP that my truck can produce. The FASS also has a lifetime warranty and an advertised 15,000-17,000 life cycle which roughly equates to 700,000 miles.

The cost is fixed by FASS, so this was expensive, but I feel a final solution to my on-going long term Air Dog failure problems which have let me down now nearly half a dozen times in 80,000 miles.

So, today was install day for the FASS pump which is the Titanium series, 165 gal/hr.

The install is straight forward.

The part that complicated matters was the facts that I had an Atlas fuel tank which is a lot longer than the sticker and covers up the area where you need to make a hose connection. That was further complicated by the fact that that Atlas has 50-55 gallons of go-juice in it so moving it around is not possible.

The other thing that complicated matters was the prior Air Dog which I had to remove, tracing wires and hoses and mounts and a bunch of stuff. And lucky me, I had previously installed a whole bunch of zip ties to the hoses on top of the tank. That isn't a show stopper since you can still access the top of the tank area, but only with hands, not with hands guided by Mark-1 Eyeballs.

But I enjoyed an added bonus, While I was messing around I grabbed the exhaust pipe to pull myself along and it was completely loose. Seems I neglected to tighten a band clamp and the whole aft section of the system was free floating and rattling around. Plus there was a pretty good gap between pipes, so i was getting some un-muffled exhaust note.

I haven't driven it since the install, so i won't know just yet, but I am hopeful it may be quieter now that everything is snugged down.

With the FASS install you connect the harness to the pump and run WD-40 through it to prelube it while it is out of the truck. Pretty cool. and I was immediately very delighted about how quiet this pump is compared to Dr. Wong's Shanghai special.

The mount kit hangs the pump from a bed bolt. It has long slots which allow for just about any mounting height you would want. Here the bolts are loose and the pump is at the bottom of its "Travel" which I used to attach the lines mo-easierily

Post by: Flyin6 on May 15, 2018, 11:06:40 PM
Is this the best location? Well, time will tell, but it is what FASS tells you to do. I will double down on this by adding a section of rubber mat just aft of the filter supported by the wheel house. This should prevent pesky rocks from making holes in those filters

Slide the assembly north and snug the bolts and just like that, she's all disappeared.

That's water all over the floor. I was tired of doing the back stroke in expensive diesel, so I washed it off, then knocked a good quantity of mud from the underside of the truck to mix with the water on the clean floor, so I could get back to playing and acting like a pig on a summer afternoon.

Anyway, some shots from ground level peeking up and you can see it does tuck up pretty well

I spent some eight hours on this install, but most of that time was messing with removal of Dr Fong's fumper and noise generator.

Did I mention that Air Dog products really suck? Probably didn't. So for the record. AirDog stuff is Chinese made junk. THe company misrepresents the product leading people to believe their junk pumps more than it does. Mine has been a source of problems constantly over 6 years of ownership. After seeing the robust quality of an American Built FASS pump. I feel like I was swindled, having purchased that Air Dog Behzhing cobbled together wanna be crap.

The tank has a sump, easily enough to see.

In the past I had a stainless steel shield I had made up covering the line, which was held in place by really large zip ties.

I had no zip ties of that size hanging around so I couldn't do anything to secure the shield.

I'll either remount the shield I made or see about purchasing the Atlas skid shield which is made for that tank

The problem with the latter choice is that the shield is made to fit the flat bottomed tank, and would not easily accommodate the nearly 2" deep sump. Now I could make it fit by just forcing it into place, but at the moment I am not comfortable with that option. So, likely, I'll just remount the skid I have used for years.

I think I'll also come up with a forward wheel house liner extension to keep flying rocks from hitting the filters. Have a trip to the farm coming up, so I'll take note of the mud pattern on the pump to get an idea of the amount of protection required.

I would simply form a plate that goes between the 2 tank mounts. If yours mounts like mine you have a bar across the front and a strap in the rear. Couple bolts in the front, zip ties in the rear and a piece of plastic plastic sheet.

I have the skid for my tank and it would not accommodate that sump well.

The week after report:

OK the pump is functioning perfectly so far. It is so quiet that I can barely hear it. The Air Fog was noisy, very noisy by comparison.

I actually have a couple of things to report on. Next the turbo/CP3/Motor-Ops tune is really working well. I just towed light to/from the farm averaging 16.8 for the trip. Please remember that that is with 37" mud tires and 4.56 gears. I think that is fantastic for an everyday rig capable of putting down 600+ at the rear wheels.

Finally, the BFG's Mud Terrains just really impressed me with their "Mud" performance. So I have been down at the farm where it has rained for three days. I finally came home having to drive out seven tenths of a mile in slippery gooey mud. Because of the traction they afford, my wheelbase and weight (9,000 lbs give or take) and that wonderful Grizzly locker, the truck barely spun at all, and that was with my pulling a trailer through all that mess. I am convinced a regular 1/2 ton truck would have remained mired in all that mess until conditions dried, but my Silverado HD with those GoodRich mud terrain tires pulled me through it all.

The wear I am getting on them is not all that great, but mud tires seldom last very long. And that Grizzly locker will definitely chew on some rubber over time, mandating a good rotation cycle, which I have established. I rotate every 5,000 miles, using a five tire rotation schedule.

So far, so good!

The raspy note is gone and the rattling sound, but it does not sound like a Duramax any more. Sounds just like an older powerstroke. I'll bet those motors had the same type compressor wheel or exhaust housing or both to produce that same pulse type sound.

I'll definitely be looking for a larger/quieter muffler.

My whole company drives fords, our excavation company uses all fords.  I drive the bosses (gas motor) and I swear the seat is hard as a rock.

I do like most of the features otherwise like the adjustable pedal height.  It makes good power, toss our trailers just fine, feels really stable while towing also. 

I like the factory ground clearance in the ford.  Where any GM truck I would purchase would need a six inch lift to get the new truck into the site, or a bunch of dirt to make a solid pad to drive over the curb and sidewalk.   

The ride really well for solid front axles, I might eat some humble pie and buy one one day.

I owned two
The first a non powerstroke 1992 F250 that I installed a hypermax turbo onto, but soon traded it on a 94 F250XL with the brand new PS 7.3

It was a tank. Lifted 4", Riding on 33's with a 4.10 gear and a 5-speed and a rubber floor mat and no electric or power anything. I drove it for years. Was a darned good truck, no complaints.

I think the 6.0's gave Ford a bad name which they quickly backed up with the 6.4 liter fiasco. I do believe this latest 7.3 is all figured out, although now that mine is finally modified, there is no way I am subjecting myself to that level of torture again within the next decade, so Chevy it will be for me.

It's been a couple years since I looked into it...

Aside from the poor turning radius, the truck pulls strong and is reliable and handles really well with the IFS it has. I think I'll keep this one in the current configuration and just drive it for the next decade or two.

The mileage continues to show me better numbers than with the stock turbo and injection pump. After a recent round trip to/from the farm with some 70 mph highway (Which hurts mileage) I ended averaging 19.3 for over 100 miles. I think that is impressive, and that was with the AC running!

Yes it sounds like a PS

However, the other day a LBZ truck passed me on the highway and had the same sound as mine did. I wonder if that is the sound of that generation turbo or perhaps he had upgraded his as well

And to add another note, I just realized this, but that 19.3 was compiled while in tune position #3 which I believe is a light tow mode. Had i been in the normal mode, #1 the truck very well may have produced an even better number.

I have some mileage loops to report

Recent country driving greater than 100 miles: 20.7mpg

Reverse of above route: 21.5mpg

Towing light, highway/country roads: 18.5mpg

Towing 4000 lbs country roads and stop and go in town: 15.6mpg

I think these numbers are outstanding, and all a substantial improvement over the pre turbo/CP3 install with newer tunes.

The truck definitely likes the S-362 and associated tunes over the stock turbo/CP4 combo.

The new Muffler installation

I purchased a MBRP 30" quiet tone full size muffler

The fit was perfect and the entire swap took only maybe 20 minutes.

I am much happier with the sound of the truck now. It is much quieter and some (Most) of the raspy note is gone. I can now stand on the throttle some without listening to that drone and loud report of what approximated a straight exhaust.

Was away for a couple more days. Towed my daughters Lexus 300 (or 350???) SUV thing on top a brand new 14K Big Tex trailer I purchased Wednesday. I make the trailer and vehicle, and a load of fresh sawn lumber stacked beneath the Lexy at say 10K.

I towed it on country roads, 40-60 MPH in tow/haul mode in tune position #2 which is heavy towing, and ended the trip showing 15.4 MPG. That's friggin outstanding! 37" tires, and 4.56 gears and running in a lower gear all the time and still over 15 mpg!

I'm pretty happy so far with the CP3 net turbo and the tunes...

Pulled the tractor on the new trailer, same route. The truck got 14.7 for the pull. Difference was air temp as far as i can figure. It was super hot the day of the 14.7 mpg pull, cooler (like maybe 80F) on the 15+ mpg pull

...Which is about what I expected from my setup.

My average speed was lower which would have affected my numbers positively. And you pulled a heavier load. However I did pull up down hills the whole way, so i'm leaning toward the possibility of this combo yielding improved economy while pulling

Parasitic drag: Yes
At that speed, once you subtract out the drag sq ft of my load it is a factor...but I don't believe it would be the dominant factor
No leaks

Another update a bit further down the road so as to speak (Mikie would like that one!)

The mileage is continuing to be really good. Country road driving has been as high so far as 21.3 for a 50 mile loop. Towing 5,000 give or take came in at 15.3 for a hilly pull of about 50 miles. Trans temp on that pull hit a high of 195 and the highest EGT I have seen, post installation of the bigger single turbo was 1136.

The thing starts every time, and is reliable. No leaks so far and with the larger mo-quiterer muffla' is OK to live with.

I am coming up on a repaint of the bumpers and tire rack though, which has me thinking of going a bit further...???

Maintenance today. Changed the oil at 15% life remaining. Mileage is now 97,600. The oil looked good. It was filtered by two Wix filters fitted to the Amsoil bypass filter setup. The bypass filter I'm using is the stock filter for a Cummins 6BT 12 valve, and the large (Half quart??) on the other mount. 3 gallons of Delvac 1300 15W-40 and the motor sounds so smooth with this stuff.

With all this hype over super synthetics with 4,5 or 6 times the wear resistance, I have to throw the BS flag. Manufacturers specify the parameters an oil must meet to allow for a breakdown free ownership experience over the projected life. That lifespan is somewhere around 300K on the Duramax with the reality often being even greater. So what does 4X, 5X or 6X get you anyway? Does that increase the lifespan of said engine by that multiplier. So can Amsoil get you 6X the engine life?? That's 1,800,000 miles. Anyone buying that? Didn't think so.

The scar rating of 1X would be good enough. CF4 or something like that (SG-4??) will get you the whole bananna. If you read the fleet test reports on the Delvac product, that particular oil is achieving some amazing results in heavy duty diesel engines. I read recently where one trucking company was pulling down their engines at 1,000,000 to 1.25 million miles for routine rebuilds and finding very little wear. Delvac dino oil is some really good stuff, and at full retail, like $17 a gallon. I got mine on sale for $13.50 a gallon with rebates making it just $6.50 a gallon. I did the whole three gallon dual filter oil change  for a bit over $47.

One gallon of that synthetic stuff is in the high thirties, so my full synthetic oil change would have cost around $150 not using amsoil filters. And what exactly more would that have gotten me? In all likelihood, nothing at all. It's just hype really in the everyday world we operate in.

I now operate everything I own (7 diesel engines) on the Delvac and I have had zero lubrication problems although some of those engines have been overheated multiple times and almost all of them are turbocharged.

I lubed the suspension and chassis, and adjusted the tire pressure to 50 psi all around. Then I got it washed. First time since summer. THe boys at the truck stop washed and waxed it for free. They said it had been too long since the last visit so they gave me that one to encourage me to stop by more often. They like me and my truck. They are good people!

So it is doing well, really well actually. And those BFG mud terrains are really holding up well. I'm trying to figure out when I put them on, because they are still well north of 1/2 tread remaining and have not let me down or gotten stuck once. I thought I'd switch out to something like the generals, but, heck, these things are doing so well, I might as well just stay with them. I run a system of replacing the two worse ones, then repeat 5,000 miles later at the next tire rotation.

Projects upcoming are a complete repaint of the front and rear bumpers and some undercarriage, the back of the topper, its roof and I'll flatten out part of the hood to reduce nighttime glare.

This is really one great truck, one that I am completely happy with and can love driving for years yet to come.

Almost 160 on mine and time for all the goodies too.

JR,
No, by the gallon. But I am set up on special pricing and a farm owner so my discounts are deep. THe only thing I can't take serious savings on is diesel fuel. (Red diesel)

I also thought it out. I don't use it at a rate that I'd feel comfortable with getting it out of an unsealed drum. When you break the factory seal, you do introduce air (moisture) and on a farm setting the chances of dust and rain are much higher. For those reasons I like keeping a shelf full of gallon jugs. I keep hydraulic oil in 5 and 2 gallon cans because that's about how much leaks before I first notice the leak happening.

I started keeping a 55 gallon of waste. Without all the farm equipment oil changes I filled it inside 2 years. Now with the excavator gobbling up 6 gallons at a time I might cross a threshold. At some point I am going to start using it as fuel, although admittedly 55 gallons is 3.5-4 days of Kubota CTL time or maybe 1.5 days of excavator time, so not a large dent, but something...

Full circle: No 55 gallon drums of the fresh stuff...

Concur. These are really high quality good trucks. Comfortable to drive, powerful, good looking, but not so easy to park...

Square D would run real nice on the used motor oil/Hyd fluid

I can't believe it, but the morimoto HID lights are on the blink...Literally.

So tonight I took C-Max over to the truck wash to get it all cleaned up and pretty for the drive to my sisters house. Returning home, at night, I noticed the headlights flickering. When I got home I had some weird blinking thing going on. the drivers low beam would flicker, then extinguish. Then it would come back on and the passenger side would wink out. they will blink back and forth alternating sides like a police car does.

Then on top of that the Amp steps stopped working, sort of. They will extend like half of the time, then just ratchet in the eextended position. THen they will close and stop working, all while the headlights are blinking. I was wondering if we picked up some demonic possession at the truck wash. So I can't say it's the headlights or the steps causing the problem, or something else in the electrical system. The alt gage shows a constant charge and I checked all the connections and found them to be OK. But I'm flat worn out, and I'm not messing with it any more until after turkey day!

How are your batteries and alternator? Didn’t you replace the former fairly recently?

Better park it and leave the windows down and hood up

Yep, grounds do real funny things.

Park it by SD and drive the sub.

Batteries are, what a year old at the most and the alternator is showing the same spot on the ammeter in the cockpit that it always has.
But there is something connecting the two seemingly unrelated problems, lights and AMP steps.

So last night I left my sisters house in the mountains of KY at 2230. (Read: really winding roads WAAY down in a valley, errr, a hollar) When I fired up C-Max I had one light, the right one (Please take note that the left was the first to cave whilst the right reported for duty!)

But as I proceeded along and we got to the place in the roads where goblins and susquach hang out the light began to dim. It got all the way down to the output of a candle, then it too died. My right soldier was obviously mortally wounded and must have been hemorrhaging, but fought the good fight and stood his post till the very end, a moment of silence please...

So, I'm not knowin' what the hay is ah-goin on here, but I started the repair process by praying over the truck. On the outside chance that some demonic spirit was hitchin' a ride, I claimed authority, legal authority over the Silvy and cast out anything that shouldn't be there. I later noted that a bag of oatmeal cookies fell out mysteriously about that time...Weird! (I just made that last part up, but U gotta admit, it sure reads well, eeh? (Or is that ehh??)

It does, but the morimoto ballasts and so forth have no special grounds that I know of...

I'll go look at the regular grounds. I already loosened all battery connections, and checked for corrosion and tightness of fittin'...GTG!

You stand officially abnonished...somethin' short of actual firin' for makin' fun of the situation and not offerin' any helpful suggestions! I'll come up with a suitable punishment at a future date...Something like having to monitor the "Dave named people who hang out there."...or worse...

Id say quit fiddle fartin around with that type of bulb set up!

Put the OE back in the truck and either get a light bar or hook your lights on your front bumper to the high beam switch for mo light?

Thats sarge's recommendation.

I agree with Nate, nothing but headaches from those lights. Run trucklites or oem....

Although I seldom if ever listen to Sergeants, you may have a point, Sarge!

Seems I have never had a straight 6 months-year without problems with the LED's, HID's and the rest of the junk out there.

OK, considering the Sergeant's advise and the well thought out advice of so many others, I threw all that nonsense out the window!

Yep, Just ordered a set of OPti-7 bulbs for it, and both sets for the Suburban

Know why?

I finally figured out why the darned things were failing so often

Reason: DRL's

Yep, safety nazi stuff.

You see the DRL's drive the headlights but at a lower voltage to produce a dimmer light

When you have LED's, the LED part of the bulb will work on a variety of voltage, going quite low, they will still burn atoms and gluons and quark particles and anti-matter. But

and like Hillary, it's a big but,

The fans in those LED's take 12 volts to cool the little trons zingin' about on the inside.

Reduced voltage would mean those fans which turn up to around 10,000 RPM are running much faster, but the volcano/rocket motor on top of the stack is still grinding out the BTU's.

The perfect recipe for electronic mayhem. Run the stuff, but fail to cool it

Solution: Pull the DRL fuse and voila, the LED's now only run when they have sufficient voltage.

Or at least that's what I think.

I want to see how those work. I have tried a few LEDs and with the led being a SMD I have found less than stellar performance. However I did not go for the high end stuff either.

I think an led would be great with the correct housing.

In the dually I bought true Phillips HiD kit from Europe. It was pricey like 220$

But in more than 4 years I never had an ounce of trouble out of them. I did also pull the DRL fuse

Not so for the flea bay hids in the fogs
