I have a pattern to make a new case gasket but they can be tough to install right.
You can see sort of whast inside the case if you go to my engine tear down in the classic posts that may give you an idea of whats there.
about the only thing that should leak out of there is grease if its not sealing.
Thanks for the replies gentlemen, I took the clutch cover off and used a socket wrench to turn the crankshaft while putting a little soapy water on the area where the gasket is not visible and while turining the crankshaft I saw some "bubbling" indicating a compression leak, <Norman;> do you think that's a correct assesment of the gasket problem. I don't want to keep the engine and then find out several hundred miles later that the whole gasket blows out.. what's a little bubbling now may progress to total failure of the gasket...
