1986 turbocharged 6.9 with head studs installed.
Have 190k miles on it. Runs great, starts with just a touch of the key, starts on cold mornings, but I'm losing oil everywhere and have high crankcase pressure.
Compression seems solid, idles perfect, and no weak cylinders.
I've heard these engines had a piston ring design flaw from the factory the leads to excessive blowby around this time.
I wouldn't mind timewise tearing the engine apart to re-ring it if I knew it would help.
Anybody ever get good results from new rings on these engines?
