Product Details
Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. If you're working on your 1951-1957 Jaguar Mark VII with the 3.4L XK6 engine, this gasket is designed to provide a reliable seal for your rebuild or repair. It's built to handle the demands of high-output engines, ensuring your engine stays sealed and performs as it should.
This gasket uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps create a strong seal against both aluminum and cast iron engine blocks, and it's designed to work without needing any additional sealants. The center layer is stainless steel and can be varied in thickness; in this case, it's set to a compressed thickness of 0.075 inches with an 85mm bore, matching the specifications for your Jaguar's engine.
This MLS gasket is a solid option for ensuring a proper seal between your cylinder head and engine block. It's built to withstand the forces generated when mating different metals, like aluminum heads to cast iron blocks, offering a durable and dependable seal for your classic Jaguar.
