I put the valve cover on the gasket with NO gasket sealer (so I could remove it to adjust valves). I had to drive the truck several times and each time, after the engine heated up. I turn the nuts on the cover to pull it down tighter and tighter. Finally, after about five-seven times, it quit leaking. By tightening the cover, I eventually made a deep enough groove in the cover to cause it to seal! I know it's not very scientific, but it worked for me. Try it!  Joe

Put it on a flat surface and go around it with a piece of paper or feeler gage to see if there any gaps between the bottom edge and the flat surface. I have a Waynes valve cover on mine and had to take to a machine shop to have them sand it flat along the bottom edge. It cost about 10 bucks, but it works great now.
Good luck

If that's the case, get two of the thick gaskets, Felpro makes them. Overlay them and cut each side with a razor blade. Best sealant I've found is 3M Weatherstrip Adhesive, just follow the instructions.
