This is a new to me truck, first analysis was how I bought it and apparently a short run.
It's in a 1986 f350 dually. Engine reportedly was "rebuilt" but I don't know who/what or when.
Second one shows crazy Cr but normal moly. Engine popped a coolant leak in a dry place shortly after oil change, seemingly a cracked head. I'm trying to choose between replacing heads or replacing the engine. If ring wear was the culprit, shouldn't Moly track high too? Could Cr alone indicate high wear at the turbo (again unknown history)? I don't know if the turbo is roller bearing or journal, it's a wastegated Banks Sidewinder.
Click Here - Cr = big problem?
Thanks for any thoughts, I am really a bit stuck on what my next step should be. I think it's pull the turbo and see if there's wear/play evident and then decide repair or replace the engine. I don't want to do the top end then have to go back in 2 years later. For what it's worth, usage is a few K miles/year expecting to haul a slide-in camper and pull an enclosed car trailer.
Best,
