Engine oil may leak externally from the cylinder head gasket. The gaskets were contaminated with metal debris from the factory – between the block and gasket and/or the head and gasket. To correct, the head gasket must be replaced and the mating surfaces on the cylinder head and block need to be inspected for chips or damage. In some cases the cylinder head will not be repairable and will need replacement.Google+

Has not been fixed, but I am noticing small amounts of oil begin to leak from between the head and the block on the passenger side of my E250. It is on the side of the engine, towards to rear.
