Oil Pan Seals ??

RPM,
Make sure all gasket surfaces are clean and dry. You are using new pan end seals right? Only use silicone in the four corners of the gasket surface where cork and rubber meet. Silicone will act as a lubricant if it has not set up and the cork gasket will squish out. If the gasket surfaces are clean and dry, the cork gasket should seal just fine. Use a very small amount of fel-co bond to hold the gasket in place on the engine sealing surface if installing the pan with the engine in the vehicle. I haven't tried the one piece pan gaskets yet, but I have heard good things about them. Hope this helps!
