Cometic Jaguar 1973-1992 4.2L XK6 .089in MLS Cylinder Head Gasket - 3.670in Bore

This is the Cometic Multi-Layer Steel (MLS) cylinder head gasket for your 1973-1992 Jaguar XJ6 with the 4.2L XK6 engine. It's designed with a 3.670-inch bore and a compressed thickness of 0.089 inches. This gasket is what seals the combustion chamber, keeping coolant and oil out of the cylinders and vice-versa.

Cometic builds these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F. This construction means the gasket seals well without needing any additional sealants, making installation more straightforward. The center layer is stainless steel and can be varied in thickness to meet different engine build requirements.

This type of MLS gasket is well-suited for engines with aluminum heads and cast iron blocks, as it can handle the different expansion rates between the two materials. It's a solid option for keeping your XK6 engine running smoothly.
