My front valve cover gasket was leaking on the rear passenger side enough to have oil weeping down the side of the engine. I pulled the cover, cleaned the gasket which was in excellent shape, and reinstalled it using a little Permatex. It leaked again so i pulled it and installed a new gasket using a little Permatex. It's leaking again even worse. I tightened the bolts pretty tight. I also noticed the bolts go into the oil passage ways. Is there any special way to install this other than using a lot of Permatex?
