Hi - I recently purchased a great car, a 540i m-tech with six speed manual transmission, a one owner car with maintenance records. The car has been running great; however, I noticed in the last week there has been an oil drip/spot ( about the size of a half-dollar coin) in the morning when parked overnight . I have had the car for about four months and driven in 5, 000 miles. Valve cover gasket was replaced 6,000 miles ago when oil change/spark plugs/coils were changed. I found no leaking or seepage around the valve cover gasket.

Does anyone know the cause of this? Thanks for any help.
