: I did have a comp test....when we poured oil in there the numbers didn't go up very high. Could this be the valves? I just wish I knew if it were the valves or piston rings, and if the turbo is on it's way to hell.
If the oil didn't make it go up it's probably the valves.... but it could be the rebuilt turbos too because certain (no names) turbo rebuilding companies are supposed to suck. Good luck with it. Take it to someone who knows what they're doing like Greg Dupree.
