Fig. 7: Information For Assigning Cylinder Head Gaskets (1 Of 2)
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.
