brewtoo, just check your top portion of the engine from the cover going to the cylinder head and see if there are traces of oil leak around that perimeter, by the way,as a CAUTION in one of the comment about HAVING TO JACK UP A CAR WITH ITS ENGINE RUNNING . NEVER NEVER DO THAT, I HOPE THAT SUGGESTION STOPS HERE, STAY SAFE AND ENJOY YOUR MERCEDES BENZ RIDE.
