Good looking GSD. I have Irish Wolfhounds, thus the Suburban. LOL Two adult girls and a five month old, 90 # boy.

My trust has wained a little bit with the 3.0 LM2..

This video has been discussed on most of the diesel engine forums. Most of the comments from the gearheads are there isn't any engine history, maintenance records, and they all commented that GM won't warranty the failure. Most of them suspect it was chipped, which GM can see in the ECM, there is a fingerprint left when you change any parameter in the ECM. Since there isn't any information other than it was blown, GM won't warranty it, the gearheads all say this should would not steer them clear of it. I have to agree, if GM won't warranty it, you should be asking what was done to it that caused the failure. The only time I have seen aluminum pistons do that, it was chipped, which causes the aluminum to either become deformed, and even cracking one of pistons due to the high temps.

I don't even know why someone would post this video? It isn't pertinent to the real world most owners live in. This engine was over stressed or got a drink of gasoline or something of that nature....

Just another "Clip" to downplay what is the most dependable engine available in these vehicles.
