If you guys ever get interested in all this sealant and loctite, rtv and antiseize and where to put it all, buy any of the Ford Engine Overahaul manuals (i.e. Haynes). It tells you exactly what to put where. If you follow the instructions developed by the Ford Engineers, then I bet you will almost never have a leak again. If you get an aftermarket gasket that isn't exactly like the oe gasket, then follow the instructions that came with the gasket. I stopped having engine leaking problems when I started reading the Ford Overhaul manual. I used to be RTV crazy too. Then I read in the overhaul manual that you should use a gasket tack on almost all the paper gaskets, not an RTV sealant. It made a dramatic difference in the number of leaks I would get. I used to slather RTV on my valve cover gaskets and still get leaks. Then I read in the manual that the gaskets should be installed dry, and guess what, I haven't had a valve cover leak since.
