A few years ago when I restored my grandfathers 1941 Chief, I found that the engine cases were cracked. I purchased new cases from Kiwi that would allow for the use of 80 inch flywheels. When I put the engine together I used James gaskets and a small amount of gasket sealer on the gaskets. I have always had a very small leak from the cases. I was running 10W50 oil at the time. I have a full set of Cometic gaskets I purchased from Starklite. Would it be worth pulling the engine to put in the better gaskets, or simply try SAE 50 weight oil?
