Yea, I have been fighting the urge to pick up a 6.2 Trail boss (While keeping the always used D-Max)(that I have WAAAAY too much invested in to ever sell) (Which I seriously need to keep) (That had better not piss me off at a critical moment of weakness) (Like when I just test drove a new 10 speed D-Max)(Like, well, like I seem to like the new trucks)(But the D-Max which is totally paid for, meaning no payments, but also no warranty)

That would mean another fluid change. Who can run a stock vehicle here?

Me, over 3 years, 65k on the clock and completely stock.

That tailgate isn’t a bad one to fix,  the latch clips are cheap on Amazon and I always just replace the complete handle so the plastic matches.

Your aren’t painted are they?

Sitting in a new truck is indeed nice. But then again there is a certain charm and feeling you get from driving something you've owned longer than kids in the sixth grade. You just feel comfortable and despite it's obvious aging, you have formed this familiarity with it's irregularities and you and that old truck strike an accord which comes out as a feeling of just being "Right."

Don. Thinking about it I think it goes deeper. It’s the values my grandfather instilled in me to take pride in what you have and to take care of it meticulously. I notice when I see someone with a well maintained older vehicle and appreciate the pride that goes into it.

It’s like driving through a really poor neighborhood. There are a few people who take pride in their lawn and their home and keep them tidy and neat. And that has nothing to do with money and everything to do with self respect.

Man, it just never stops. Today the anti-lock warning light came on along with the traction control warning light. The DIC displays a message "Service Trailer brake, along with a couple more messages.

Darn, I'd like to keep from buying new if I can help it!

I had a trailer brake service light at one time on my 2013. Would lock up trailer brakes at the slightest tap of the brake pedal regardless of the settings. Was bad enough we had to stop in the middle of the road and unplug the trailer plug just to be able to pull into a parking lot.

Replaced the "trailer tow relay" ($30 from rock auto) and have had no more issues since. The relay is located above the spare tire location under the bed. May be worth a look. Cheaper than a new Dmax

Well, I tried to get started working on the truck today, but my son kept me busy on his "New" 2007 Silverado. When I finally got to it, first thing I noticed was a puddle of radiator fluid on the ground! WTH is going on! This thing decide to just up and quit on me???

Similar to others, we’re almost 3 years 45k into our tacoMa and it’s bone stock.

Also Chief, We are still interested in buying your duramax if you want to buy a new truck.  Feel free to call if you get into heavily looking at buying another. We had a conversation last week about wishing we never had sold our 2007 duramax.

So today I made big strides. I pulled the radiator reservoir off and installed a new one, then cleaned up the air cleaner, having pulled it, then reset the trouble codes, and just like that it is all back to working properly!

And reinstalled the new radiator reservoir along with all of the air intake system.
I replaced the coolant tank because I had been getting a "Coolant level low" message which this new tank has fixed

Now I don't know what the heck is going on, but my anti lock brake warning light is off along with all the messages, and the traction control light is also no longer illuminated!
Not sure who prayed over the truck to expel the demon, but all those messages including the "service trailer brake" have all gone away.
So, for now I'm good, I think...Well except for that left headlight that went out!!!!!!!!!

The plastic lid grenaded some time ago so it had been pulling from above as well as from the fender. Looked like a mat of dust. That accumulation on the filter hat was from the underside. I had rotated it to see if anything was down there and discovered the mossy camo stuff.
Dave, the filter was slightly blackened, confirmed by the sooty appearance of the stuff that came out in the wash. It all came out easily though, and the inside of the air piping was as clean as a whistle (Which apparently stays pretty clean)

I need to buy a new intake system for mine. The filter rubber jacks broken down and is disintegrating or sticky to your fingers. It’s a sb intake for stock location.  I’d like a new intake box and so forth   


Just can’t stomach the cost of a new system!

I may have another issue, head gasket(s). Not sure.
I was thinking about that puddle on the floor. And when I pulled that little hose off the top of the reservoir it was under some pressure.
I started to read about that and some folks mentioned head gaskets lifting. Since I baby mine, I would doubt it, but maybe??? From what I read the failure occurs at the rear outside corners where the head is super close to that very hot up-pipe. When I was checking it, sure enough that's where the fluid was concentrated. There was a very small leak in the coolant hose above it where I blocked off the feed to the EGR and I may have talked myself into thinking that's where all the fluid came from, but I am not so sure at the moment.
I read where another indication is a super hard upper radiator hose (I suppose from all the pressure inside). Well In checking mine, it is pretty firm, but I would not describe it as super hard.
I guess I'll have to get scientific with it and figure this out.
I would really, really, no, REALLY, hate to have to replace head gaskets...

Can’t you put a pressure tester on the system also to see if that is an issue

I also have an idea or dream of testing for exhaust fumes in the Rez tank

I as well have random leaks.
Both sides. Not regular.
But every now and then I get a low coolant message.
Like you my upper dad hose is firmer than should be in my mind.

I blamed mine on 2006 and 300+K miles.
I have often thought about frost plugs being the culprit.
I however am freshening one of my LBZ’s up and will include headstuds.

Hopefully you don’t have to go that route.
I’ve been adding coolant for probably 8-10 years now though so mine hasn’t been real serious.
I just don't want to wind up missing a digit or limb.  I can sometimes get in a hurry to get results.

Yea, this one is not serious at all. I've seen vids where the radiator tank is black with carbon. Mine had none. Once a head gasket is blown, it is blown. And I hear that about 90% of the D-Max heads are warped as much as .014" when this happens. I have also learned that this is fairly common in duramax engines

So the cure is to pull the heads and send them off for machining. Head gaskets come in three thicknesses, marked "A" "B" and "C". The "C" gasket is the thickest allowing for machining of the heads to space the valves up a bit further away from the piston crowns. So the heads get pulled and machined, then new head gaskets after a good block sanding of the block surface, then ARP studs torqued to 125 ft/lbs which solves the problem even for higher boost.

Merchant has a kit for $1145.

If I determine that the head gasket(s) is/are the issue then I am at a crossroads.
The anti lock warning light came back on today as did all the other junk.
So, if the gaskets have given up like some RINO republicans then:
1. I sell it or
2. I trade it or
3. I pull it down myself and repair or
4. I stroke the rather large check to have it done...Thinking $3000-$3500 ish

If I do replace this truck, then the next one will remain close to stock and I'll get a dedicated lower optioned one ton single or dual wheel Chevy or Ram.

I find it hard to believe that a low mileage LML that hasn’t been beat on has a head gasket issue. So many out there with much higher mileage that have been beat on with no issues.

But hey. I guess it could happen.

I’d like to see the head gaskets done personally.  I know that’s the next step in mines future, I’ll take the how to write up,

Plus you sell you’ll loose lots of value invested, you loose the off-road ability the new truck won’t have. The tow pig option can be addressed in other ways cheaper then a new truck


I did have a friend drive back from Tennessee with a new 1 ton Cummins with a lifetime warranty on drivetrain. That was interesting enough!! To think hum. Could I drive a dodge?

Well, this morning I am leaning toward the massive head gasket job. My idea is to create a DIY write-up for others to follow and document. I am not sure I have a head gasket problem just yet, so all this is speculation. But with the possibility looming up there, contingency plans are apropo'

Just sell it to Turner, he’ll ship it to Ken to fix and you can go buy a newer one......  :wink:
No don’t sell it to me, I don’t want to go through the hassle of licensing it in this stupid state. Neighbor is dealing with that nonsense on his Jeep now, and it only has 35” tires and maybe a 1” lift.

I think that unless you were towing heavy, daily, and ignoring the egts while on the 200 horse tune, that it's probably not head gaskets. I've whipped on mine pretty hard and not lifted heads yet....yet. LMLs are pretty tough.

Heck, you could just add to your Nissan fleet and get another Titan, this time an XD with the Cummins.

OK, so I've investigated this some more.

No additional anti-froze around the corner or anywhere on the head to block mating surface. The upper rad hose was firm but not hard last night and soft this morning. From what I read, the upper hose is usually found to be hard in the morning after the evening's drive (Residual pressure)

But

When I went out to check the thing this morning there was oil all over the floor beneath the engine!!!!!!!

Ya, another problem. but I think I have it traced down to a tiny rubber pipe on the lower left side of the front engine cover. Seems to be really wet around there and aft of that spot. Leaked quite a bit, so I am suspecting a hole in that hose.

Did some research on the anti-lock/ABS light along with the stability control light and message.

When I replaced the glow plugs, I also realigned the steering column. Remember when I had the steering wheel disconnected and spun it up like I was hand propping a Beech 18? Well the steering wheel sensor is probably sending a misalignment message which also affect the systems that have suddenly failed.

Course of action: Going out tomorrow to purchase a medium-good ($300ish) OBDII analyzer. I'll start pulling codes and run them down. I am now on a mission to get this thing back to 100%. It has been shock therapy looking at the prices of new trucks. As scary as lumber prices and the thought of a pedophile and a communist running our great nation!

I don't think doing the heads are that bad, once you lift the cab off.

Hope its not the head gaskets, but seems always a little something.
