My 30 Tudor leaves a patch of oily liquid of the garage floor. Not a LOT...but enough to cause concern. I pulled and resealed the oil pan, and installed the "Real Deal transmission seals at both ends. It is not coming from gasketed joints. When I put a drip pan underneath it drips for a day or so after a drive but does not leak at all after that until I drive it again and heat the engine up. The bottom of the engine and transmission get 'damp' with a fine film of oily liquid that drips from the lowest points. The oil and transmission fluid levels remain EXACTLY the same...no loss at all! It can sit cold for weeks without a single drip. Can this be blow-by through the oil filler tube cap creating a fine mist of oil that runs down the driver's side of the engine and is then distributed toward the back by air-flow while driving?
