My motor is leaking oil (just a drop or two on the floor in the
garage) where the filler tube meets the case.  Looks like an attempt
was made to "seal" it with RTV, or perhaps the proper gasket was not
at hand when the current engine was installed (it's not the original).

Is this a common area of leakage (i.e. maybe there IS a gasket and it
leaks anyway, and the RTV was globbed on later as a "fix" ??
