Cometic Buick 3800 Series II/III V6 .084in MLS Cylinder Head Gasket - 3.840in Bore - LHS

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically designed for Buick 3800 Series II and III V6 engines. It features a 3.840-inch bore and a compressed thickness of .084 inches, making it suitable for a wide range of GM vehicles including the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro. This gasket is crucial for maintaining proper compression and preventing coolant and oil leaks between the cylinder head and the engine block.

Cometic builds these gaskets with 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 varying surface finishes without needing additional sealants. This construction is ideal for engines with aluminum heads paired with either aluminum or cast iron blocks, as it can manage the stresses that arise from dissimilar metals. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .084 inches on this particular gasket.

When you're rebuilding the top end of your engine, a well-made head gasket like this Cometic MLS unit is essential for a reliable seal. It's designed to handle the demands of higher output engines, ensuring your engine runs smoothly and efficiently.
