Information for assigning the cylinder head gaskets - AH01.30-P-1000-06V
WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 2012 Mercedes-Benz GL550, 2012 Mercedes-Benz GL450, 2011 Mercedes-Benz ML63, 2011 Mercedes-Benz ML550, and 2011 Mercedes-Benz ML350. However, it is still accessible from the selected car via links, so may be relevant.
Engines 112, 113
The assignment of the applicable cylinder head gasket on the left and right to the matching engine can be verified when the cylinder heads are installed at the visible round notch between cylinder head and front of crankcase.
Incorrectly installed cylinder head gaskets, e.g. with marking B instead of A, cause a knocking engine noise, particularly at high idling speeds, as the pistons touch the projecting cylinder head gasket. If a complaint exists, replace cylinder head gasket.
