I've had the blower off of my car 3 times. Every time I take it off, the intercooler has oil on it and there is oil in the lower. The culprit is the pcv system. How do I solve this problem. The simple solutions seems to be plug the holes in the intake tract and vent the valve covers. Suggestions?? The blower is off of my car now, so this should be an easy problem to solve.
