WORN OUT or ABUSED? 368,000 Mile 5.9L Dodge Ram Cummins Turbo Diesel Engine Teardown. (It Still Ran)

Today I'm tearing down a 5.9L Cummins Turbodiesel from a 2006 Dodge Ram 2500. This engine is from a 368,000 roofers truck that I bought for parts and IT RUNS! But, just because it runs, doesn't make it a good engine. It ran terrible, misfiring constantly and pushing a LOT of crankcase pressure known as blowby, out of the oil cap hole. In this video I tear it all the way down to find the root cause of its symptoms and see what parts survived the likely rough life this truck lived.

Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!

Every single week, I post a new teardown video of a blown up, failed, or thought to be bad engine to figure out what went wrong, why, and what could be salvaged from it. Here are a few of my favorites:
