2007 Mercedes-Benz GL450 Question: Oil Leak



bobbynewman, Madison, WI, December 02, 2010, 16:07

There is an oil leak at the end of the valve cover facing the rear of the car. There appears to be a black plastic round cover about 1 1/2" in diameter where the oil leaks around. Anybody know what that is? Is it just a plug of some kind? Part of the valve cover gasket?

    I had a similar leak and it was the cam plugs. I had them replaced and no more leaks.
