Pulled the supercharger today to replace my lim gaskets. And what I found was oil on the underside of the supercharger at the bottom of the pcv valve. I also noticed that there was something jammed in the pcv breather hole. It was the plastic cone or whatever that thing is that goes right underneath the pcv valve. Is that peice of plastic supposed just sit in there with the pcv valve on top of it? Im also guessing my pcv valve is bad since there was supercharger oil everywhere, would I be right? Any help, thx.
