So it is a miracle that truck even ran. The deeper into it I get the more problems I find. So far the injectors were bad, which melted a piston. Then I sent the Cp3 to get checked out, it had one seized piston, another sticking, and only one working properly. So I got a new one of them. Then I check on my heads at the machine shop, he tells me the drivers side had 4 bent valves and they were not from the same cylinder as the melted piston. They were from a couple different cylinders, I didn't ask which ones. Two were very noticeably bent and two were only very slightly bent.
After alllllllllllllll those problems I have to say I am amazed the thing ran as well as it did :spit:. I mean you would think with 4 bent valves, a failing Cp3, and dying injectors that thing would have ran HORRIBLE! But it didn't, it idled smooth and smoke free, and would rev all the way to the limiter without a problem. The only clue something was up was it felt sluggish :baby:. The Duramax is an extremely resilient engine, I have learned that! This has been quite a learning experience for me, and not always a happy one :rofl:
