1985 Jeep CJ-7 mileage: 225,000. My engine is blowing oil out around the distributor shaft, oil dip stick, oil pan, and up into the air filter. A compression check shows approximately 160 PSI, dry to 175 PSI wet. All vacuum lines intact and pulling approximately 20" HG including through the PCV valve. Would this be a piston and ring problem or just the head (valve seals) or something else?
