Oil Pan Seals ??

Cork and silicone don't mix. That goes for valve cover gaskets and intake manifold end seals which most people don't use with a high perf intake manifold anyway due to the lack of locating pin holes in the manifold (anyone want some? I think I have two or three sets laying around!). You should be able to find Felco-bond at any auto parts store. If you can't, just look for "Gasket Adhesive". I know what your talking about regarding the tar like sealant your dad used. I might be wrong but I thing it is or was called Gaskacinch. It's an excellent adhesive/sealer but is a bear to get off if you ever want to replace the gasket. Iv'e never had a leak installing a cork gasket dry, but I do mean absolutley dry, no oil or big hacks in the sealing surfaces. BTW, I have a few extra sets of new 360 end seals, PM me if you want them and I'll stuff 'em in an envelope, free of charge.
