Looks like the motor is done

Making 10.8 psi at the manifold, no misfire, but under boost its blowing oil out of the valve cover gasket. Getting a ton of crank case pressure. I measured compression low on one cylinder and when I dropped oil in the compression came up, pointing to piston rings. It also dynoed at over 100hp less than before. Going incredibly rich on boost. Looking at the mass airflow readings, seems like all the boost is going straight past the piston, causing very rich afr. Looks like Ill be building a new motor.



Planning on doing upgraded piston rings and the M50 manifold. I haven't decided yet on studs and head gasket change.
