Cylinder Head Gaskets

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 BMW 760Li, 2007 BMW 760Li, 2006 BMW 760i, 2006 BMW 760Li, and 2005 BMW 760i. However, it is still accessible from the selected car via links, so may be relevant.

The cylinder head gasket is a triple layer steel gasket with rubber coating. This gasket version is already established in previous engines (N62).

The cylinder head bolts for the N73 engine are M10x160 necked-down "stretch" bolts.

NOTE: These bolts should always be replaced when repairs are performed.

The lower part of the timing chain housing is bolted to the cylinder head using two M8x45 bolts (arrows above).
