Check out the youtube videos on the turbo cleaning. Very common issue with the EGR Duramax engines. Thought mine was sticking, turns out it was the tune.

shop started pulling the motor apart. pass side is alright i think. intake runners are nasty. y bridge is nasty. all 4 injectors on that side are out. driver side has back 2 injectors stuck in head. one of the guys said that it may need injectors by looking at the tips. will have them tested and see for sure. but fingers crossed there is nothing wrong with them. i can’t imagine that there is with how well it cranked and didn’t smoke. etc.

thoughts?

good thing i decided to do this. will give me an opportunity to clean all intake related hardware.



motor still has cross hatching!! carbon rings will get cleaned up as well.



all oil related surfaces look great. no sludge build up or caking. all very clean.

Looks pretty clean, did you ever come up with a mileage on the motor? Still in sure right?

i have 2 different numbers.

160k on the odometer (that i didn’t see) but was told from the seller.
233k in the fall of 2015 from carfax.

so who really knows..

it ran great. need to load EFI autocal on the computer so i can read ECM data from when it was running.

are you going to drop the pan look at the mains and rod bearings?

really want to get another upper oil pan since this one is corroded so terrible. and possibly a deeper lower pan. or just a new one that isn’t dented (from removal i’m sure)

so when that happens.. may pull a cap and see.

That is nasty!

So, for all we D-Max owners, what is the culprit? Oil coking I assume originating from the turbo? The PCV? somewhere else?

my best guess is PCV mixed with EGR and idling for long periods of time. don’t know about others.. but LBZ PCV enters literally 2” in front of turbo opening (post air filter). EGR is about 1’ before y bridge. so not only does EGR get mixed in with oily air, that same PCV air goes through all turbo piping and IC. ultimately it settles out (condenses if you will) on the turbo boots where they ridge, causing them to deteriorate rapidly.

so.. if you have a trusty 6.6.. my recommendation is PCV reroute immediately (you can see why) and if you’re building a strictly off-road vehicle like me  :laugh:  remove the other part too.

it also contributes to the veins in VGT becoming stuck if not driven/actuated all the way through. (from my understanding..)

easiest, quickest way to remedy some of this is with PCV reroute to just dump under the truck. every 18 wheeler you see does the same thing. as well as those silly 6 cylinder inline diesels that seem to last so long.

I had mine re routed to under my truck, the issue I created was white smoke at startup and moderate acceleration, I spent months trying to figure out why I was getting the white smoke all of a sudden

Undid my pvc reroute and the issue instantly stopped

I undid the stupid plug T.  Took 3/4 hose down the block driver side and dumped into an eBay catch can.  From that point on it started to blow white smoke.     

Not sure why, not sure what I did wrong,  it’s all connected back up and I have just replaced elbows a few months back

white smoke like.. out of the exhaust or from under the truck?

that’s weird. buddy of mine suggested i do it as well but made no mention of smoke issues from when he did it on his LBZ.

Out of the exhaust,   I had never found anyone with a duplicate experience.   I am not saying to don’t follow the pCV reroute.   I was hoping someone more educated than me might suggest why or what I did wrong

how large was your pipe?

(on the motor guys.. come on)

i’ve heard of them being too small or restrictive/kinked which causes a buildup of pressure inside the crankcase. so even though it’s ‘open’ it’s not allowing all of it to escape

I am not sure on the size it might have been 1/2 or 3/4.   What size do these kits come with?   The length and going into the catch can could have also been an issue

It could easily pass for new!

This is, of course, unsettling to me

I'll explain

I like the D-Max and am used to the power the thing produces day in and day out.

I got to drive the Burb with that skinny 6.0 in it again today. We found the leak and parts on order, but drive it I did never the less.

With the 4.88 gears and the cam and the this and the that's, it's downright slow compared to my D-Max. I am wondering that if I turbo charge it, if it will even approach diesel torque then?

I sadly admit it, but I may be looking for one of these for the 02 Burg as well. Just not a gas-happy guy I guess.

thanks guys. been lots of work and parts hunting. now i have to find a set of injectors for the 6.6 as only 3 of them passed the test. i may have an LBZ motor for cheap that had a knock. will have all accessories and 110k upper and lower oil pan. not building either, just using  parts i need from one to finish the other. we shall see. waiting to hear back as we speak.

don, go ahead and get an LBZ/LMM and be done. don’t be scared of a 2wd. they’re very easily converted. and harnesses can be made for electric tcase. ken in FL with stand alone solutions is your guy.. just sayin.

I think I just may. Judging from driving it a little, it just feels puny beside the D-Max. It would have to double or triple in torque to start to curl my lips into a smile.

yessir. they adjust pressure on the spring and ball to allow for a more custom setup for shift resistance.
