I am trying to figure out the source of a a leak. I recently acquired a '71 IIa and it has a decent leaking that looks to be dripping out of the hole at the base of the flywheel. The fluid looks like engine oil. I've only had the car for a day so I am still getting acquainted with it. The engine is new and seems in great condition. No other signs of leakage from elsewhere in the engine. Any ideas? Maybe a rear main seal?
