ACCELERATION IS FINE NO KNOCKS
PCV IS FINE
RUNS GOOD
WHEN OIL CAP IS REMOVED PRESSURE APPEARS HIGH
WHAT COULD BE THE PROBLEM
When you say pressure appears high, what happens when you remove the cap? Oil spitting out, the sound of z "heavy breathing"?
You say PCV is fine, I gather it shows suction when removed while the engine is running. So put it back.
With the engine idling, remove the oil cap and block off the opening with yout hand. Do you feel pressure then, or suction? Or neither? I think I would expect either neither, or slight ****. In which case, all is good.
