Today's question is, I have a few gaskets I'm not sure if I need to add a gasket sealant. one being the head gaskets , they are an asbestos type material ( NOT metal) , Not sure if I need to use copper sealant or leave it alone with no sealant, another is the the final drive gear cover gasket ( part number 11372-463-306 ) goes on the left side rear of engine, and a few others..
Don't use any sealant on the head gasket, just make sure the mating surfaces are clean. As for the final drive.... some people say that nothing is needed. I on the other hand feel that a thin coating of silicone sealant doesn't hurt.
