Cometic Jaguar 3.8L XK6 .084in MLS Cylinder Head Gasket - 89mm Bore

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for engines that need to perform, offering improved sealing performance for high-output applications. This gasket is designed to work with aluminum heads on either aluminum or cast iron blocks, handling the stresses that can arise between different metals. It’s a well-made part that doesn't require any additional sealants, making installation more straightforward.

The construction here is notable. It uses multiple layers of stainless steel for strength and corrosion resistance, with an embossed and Viton rubber-coated outer layer on both sides. Viton is a heat-resistant material, capable of handling temperatures up to 482°F (250°C), which is crucial for keeping a tight seal under demanding conditions. The center layer is stainless steel and can be varied in thickness to meet specific engine requirements; this particular gasket has a compressed operating thickness of 0.036 inches and an 89mm bore, suitable for the Jaguar 3.8L XK6 engine, as well as certain Mazda models like the Miata and Protege from the mid-90s.
