check the back valve cover, there will be a rubber hose coming from the upper plenum that connects to it. i broke the hose the first time i switched the pcv valve. they seem to be brittle with age. i just ended up replacing the rubber hose with a thick silicone hose from an import performance place and have never had a problem yet.
