Product Details
This is a Cometic Multi-Layer Steel (MLS) head gasket specifically for Jaguar 3.8L XK6 engines with an 88mm bore. It's designed with a compressed thickness of 0.140 inches, making it a solid option for rebuilding or repairing the top end of these classic Jaguar powerplants.
Cometic builds these gaskets using 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 tough sealing environments and various surface finishes without needing additional sealants. This construction is ideal whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can handle the shearing forces that can occur between different metals.
This gasket is a well-built component that offers reliable sealing for your Jaguar's engine. It's designed to provide maximum sealing performance for engines that see higher output, ensuring a strong seal between your cylinder head and engine block.
