So as I continue my quest to stem the flow of oil outside the engine... :-p

I have a small leak from the bottom of the crankcase, right along the seam. I figure no problem, I'll pull the engine and replace the crankcase sealing gasket. This will give me the opportunity to put a whole new gasket set in the engine, which I wanted to do anyway.

So I'm about to order an engine gasket set, and notice there is no crankcase seal listed. I bust out the service manual, and sure enough, no crankcase seal is shown in the blow-up.

So if these two halves of the case fit so well they don't need a gasket, what is the best method to patch an irregularity in the case seal?
