Cometic Jaguar 3.4L XK6 .040in MLS Cylinder Head Gasket - 83mm Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket specifically for Jaguar 3.4L XK6 engines with an 83mm bore. It's designed to provide a strong seal between your cylinder head and engine block, which is crucial for maintaining proper compression and preventing coolant and oil leaks. This gasket is built to handle the demands of higher output engines, offering a reliable seal without needing additional sealants.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This makes it suitable for applications where aluminum heads meet either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is uncoated stainless steel, and the overall compressed thickness of this gasket is 0.040 inches.

This gasket fits a range of classic Jaguar models, including the XK120, XK140, XK150, and various Mark series vehicles from the late 1940s through the late 1960s. Ensure you have the correct bore size and engine displacement for your specific Jaguar application.
