The cylinder head gasket is a multi-layer steel gasket with a
rubber coating. This type of gasket has previously been used on
other engines.
Note
Once work has been carried out on the cylinder head gasket
surface, the cylinder head gaskets must be replaced with
gaskets of a different thickness. The cylinder head gaskets on
the B36 and the B44 have different hole diameters. Once fitted,
it is possible to tell the cylinder head gaskets apart.
This is because the B44 gasket has a 6 mm hole in a flap on the
outlet side of the cylinder head gasket.
Cylinder head bolts
The cylinder head bolts for the N62 engine are always
M10x160 necked-down bolts. These bolts should always be
replaced when repairs are carried out. The lower part of the
timing chain housing is bolted to the cylinder head using two
M8x45 bolts.
