Cometic Jaguar 3.8L XK6 .027in MLS Cylinder Head Gasket - 89mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for the Jaguar 3.8L XK6 engine with an 89mm bore. You get one MLS head gasket with a compressed operating thickness of 0.036 inches, designed to handle the demands of higher output engines. It's constructed from multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction means the gasket can withstand the forces between aluminum and cast iron blocks without needing additional sealants.

The multi-layer design gives this gasket increased strength and resistance to corrosion, while the stainless steel layers allow it to rebound. The Viton coating on the outer layers is specifically chosen to meet the challenges of tough sealing environments and varying surface finishes. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the 0.027 inch thickness of this particular gasket. This gasket fits a range of vehicles, including models like the Jaguar Mark IX, Mark X, and XK150, as well as certain Mazda 323, Miata, and Protege models from the mid-90s.
