My 1995 S600 has an oil leak. The oil is leaking from an oval shaped plate which is located near the bottom of the oil filter housing. The plate has a bolt through it which is located in the center of the plate. I am sure there is some type of rubber gasket or grommet below this plate that needs replacing. Does anyone know the name of this part or a part number? It only leaks while the engine is running.
