Lee and others; The way that I seal valve covers ( I have used both the stamped and cast aluminum style) is that the covers get soaked in carb cleaner to remove all paint and old gasket material. I then wash it with de-natured alcohol, to remove all traces of the carb cleaner. You can also clean them by bead or media blasting. Bottom-line: they look brand new when the covers are what I call clean. For stamped covers, I then paint the outside with high temperature gloss header paint. After the paint drys, I take the new gaskets, coat the mating sufaces of the gasket and the cover with 3M weatherstrip adhesive or Mr Gasket Gasket Cinch. After they get tacky, I position the gaskets in place. I then wipe a small bead or fillet of silicone between the gasket and the cover (vertical walls). Before I install the cover, I brush a film of white lithium grease on the mating surface of the gasket. The grease allows the cover to be repeatably removed and re-installed without tearing the gasket. I brush on a new film of white lithium grease before I re-install the cover each time (cut a hole in the center of your white lithium grease-lid and put an acid brush in it.) One more thing to check: remove the valve cover spring-bails and make sure they are flat, and that the ends are not bent. The ends should be co-linear. If they aren't, bend them so they are so when they are installed in the heads. I've never had one leak-- ever!

Do you have any suggestions for stopping the leaks????
