oil is a mess...you must use a product called "foamy engine brite" blast it clean with a pressure wash, park in the sun and go and get lunch...when you come back you may just use some WD-40 to chase away any remaining moisture from the high voltage components....then start the car and carefully examine where the oil is leakin' from....use an inspection mirror (available at NAPA) if you have to~

That will be first thing after it cools off a bit. Thank Roy.

Valve cover gasket failures are the most common problem, if yours have never been replaced now would be a good time to do so.
