I'm the new and second owner of a 1979 L-82 4-speed. This is my first Corvette (Owned a '69 Camaro for 14 yrs.) and I am experiencing an annoying problem. I have an oil leak that seems to be coming from the back of the engine (rear seal?) Has anyone had any experience with this type of leak? What is the fix? Does the engine have to be pulled? Any help would be appreciated.
