Duramax carnage

[Nyoest]

Customer had some engine noise. Here's what we found when we pulled the pan. Poor sob.

 

[BIGNASTY]

So whats the problem??? I always have a few extra nuts and bolts after working on a truck GOOD TO GO

 

[EMAC2]

wow! was this stock or running on a tuner?

 

[mainer29]

What model year is the truck and how many miles were on the engine.

 

[SierraRam]

Turned into a coffee grinder! Thats gonna leave a mark.

 

[Nyoest]

Stock 3500 with edge. About 175k on the clock. we haven't had an opportunity to pull it down but I'm anxious to see what is left in the block.

 

[RolandJ]

its still good you can use it on the rebuild :-laf

 

[Mikey-KE7LBB]

Some engine noise?? :-laf

Some engine noise?? :-laf

Actually according to the passengers it really wasn't that loud or noisy. Just realllll smoky.



Stay tuned. I should have some 4 bt failure pics tommorow.

 

[Mikey-KE7LBB]

Awesome!! I love to see carnage!! As long as it's not mine! !:-laf

 

[firemansdiesel]

my friend who has a machine shop has never seen a duramax in his shop..... im sure the owner of that motor did something abnormal to it..... with the tuner, that does not help... .

Well, I'm sure that since your buddy has never seen it, it couldn't possibly happen. Has he seen a HPCR 5. 9 drop a valve seat? Has he seen a dt 466 loose liner seals? How about vp 44's, has he seen one of those bad? Any engine can have any kind of failure, despite the best maintenance.



As to the failure we still haven't torn it down yet. When the new long block gets in ill swap components then I'll be a lot closer to diagnosing the failure. The customer was towing a large trailer at highway speeds for a long time before the failure. I'm thinking either an injectors failure hydro locking a cylinder, valve stem breaking or ?????

I'm curious as to whence the shrapnel came.

 

[HOBrian]

WOW!!! That's gonna be expensive!!

 

[WDixon27]

looks like most of it was a piston at one time

I'm curious as to whence the shrapnel came.

 

[Nyoest]

Yes as far as I can tell it was, at one time, a piston. I bet the rod looks pretty good as well!

At least they make the engines easy to pull. We can have a dmax on the ground in about four hours now. Worst part is the gd starter.

 

[KBurgoyne]

if its an 01 or 02 i got 20 bucks on a cracked injector body turning the injector into a blowtorch and melting the piston. they do that and when GM found out about the problem they put a 220000 mile warranty on the injectors. so after you pay for the rebuild they will send you a new set of faulty injectors.

Just can't beat a deal like that, eh?
