ML 350 Spark plug and Cylinder Head
a) How many spark plugs does it have in the engine? I want to replace them so am looking for this basic information.
b) Front Cylinder Head covers are leaking engine oil a bit. Dealership recommends resealing the front covers and camshaft solenoids. They do not see any crack in the cylinder head. They would off course replace the gasket. Would this solve the problem? Or it can reoccur and probably require replacement of cylinder head and / or solenoids?
Thank you,
Raj
oil leaks at the front of the cylinder heads is a common leak on this engine. Have the dealer reseal the cam solenoids and chain gallery covers (plates).
