3M makes a product called "Super Trim Adhesive" (commonly called Gorilla Snot in the business) that I've used on stamped and aluminum covers, and rarely get a leak. I have assembled entire engines with it, and the stuff holds like, well, Gorilla Snot. It isn't made for this application, but I read years ago some top engine builders use it, and I see why. Coat both sides of whatever gasket you choose, and even cheaper ones should hold.
My second favorite is Permatex Hylomar (spelling?) It holds well, and comes apart easily down the road.Last edited by donsrods; 01-12-2006 at 05:12 PM.
