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

Starting with a compressed operating thickness of 0.045 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for the demands of Buick 3800 Series II and III V6 engines. It's specifically designed for the left side of the engine and features a 3.840-inch bore, making it a solid choice for rebuilding or replacing head gaskets on a wide range of vehicles, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro.

The construction uses multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in harsh sealing environments. This design means the gasket doesn't require any additional sealants, and it's suitable for use with both aluminum and cast iron engine blocks, effectively handling the shearing forces that can occur between different metals.

The center layer of stainless steel can be varied to achieve different thicknesses, and in this case, it's set to provide the 0.045-inch compressed thickness. This gasket is a well-built component designed to provide maximum sealing performance for engines that are pushed a bit harder.
