Does Your Valve Covers Have Baffles
The post about the PVC system. If your valve covers don't have baffles in them, that could cause your problem too. How about some feed back from the guy that posted this as to what you've tried so far. If you find it be sure and let us know. Just out of curiosity, what brand of gaskets did you use and what kind of gasket sealer. Felpro and Permatex Ulta Blue is all I'll use on an engine.
