Cometic Buick Series 3800 II/III V6 .045in MLS Cylinder Head Gasket - 3.840in Bore - RHS

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket, specifically designed for Buick Series 3800 II and III V6 engines. It has a bore size of 3.840 inches and a compressed thickness of 0.045 inches, intended for the right side of the engine. MLS head gaskets are built to handle the demands of high-output engines, offering a strong seal without needing additional sealants.

Cometic constructs these gaskets from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating is applied to both sides of the outer layers, helping to create a reliable seal against various surface finishes and operating conditions. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.045 inches found on this gasket. This construction also helps the gasket rebound and resist corrosion, making it suitable for applications with aluminum heads and either aluminum or cast iron blocks.

This gasket fits a wide range of vehicles, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro from the mid-90s through the early 2000s. It's a well-built component designed for reliable performance in demanding engine environments.
