I have posted about this a bit before. Car is in the signature. It is building some pretty serious crank case pressure, i replace the PCV, checked the plugs, they are clean, no smoke out the exhaust, but under wide open throttle, it will blow the pcv and grommet out of the intake, under idle, you can feel air coming out of the oil fill neck and dipstick. At idle, boost gage reads 12-14 pounds of vacuum. any suggestions? it had been mentioned the s/c might be plumbing boost into the crank case, where would i check this. you can feel vacuum at the PCV if you pull it, and put your finger too it, the car runs great, other than this.
