Product Details
This is the left-side cylinder head gasket for your Buick 3800 Series II or III V6 engine. It's a Multi-Layer Steel (MLS) gasket with a 3.840-inch bore and a compressed operating thickness of 0.030 inches. This gasket is designed to handle the demands of high-output engines and fits a wide range of GM vehicles from the mid-90s to early 2000s, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro.
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 harsh sealing environments and various surface finishes. This construction means the gasket requires no additional sealants and is suitable for mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals.
