It runs, but it's bizarre. Sometimes it runs great and other times it runs like ass and wants to stall but, if you give it gas it will staying running. The compression test shows the rear bank pressures are at threshold for two of the three cylinders and slightly below the third (145 psi). My pre cats were clogged due to burning oil from. A bad PCV valve. My buddies dad who is a master mechanic believes it's massive carbon on the valves. The rear pre cat was pasted clogged to the point you could only see light come through a few holes in the honeycomb. I am going to try to pour seafoam in the intake and see if that clears it up, but I don't think it's going to work. My thought is if it was bent/burnt valves then it was run like ass all the time. The only other thing it could be is a cracked head but, I don't know if it would like good sometimes and not other with that.
