Cometic Buick 3800 Series II/III V6 .120in MLS Cylinder Head Gasket - 3.840in Bore - LHS

If you're rebuilding the top end of your Buick 3800 Series II or III V6 engine, getting the cylinder head gaskets seated correctly is crucial for a reliable seal. This Cometic Multi-Layer Steel (MLS) head gasket is specifically designed for the left side of your engine, featuring a 3.840-inch bore and a compressed thickness of 0.120 inches. It's built to handle the demands of both aluminum and cast iron blocks, making it a versatile choice for many applications.

Cometic constructs these gaskets from multiple layers of stainless steel, which gives them 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°F (250°C) and works well with various surface finishes. This construction means the gasket can rebound effectively and doesn't require any additional sealants, simplifying installation and ensuring a strong seal right out of the box. It's a well-built component designed to perform under pressure.

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. Always double-check the fitment guide to confirm it's the right part for your specific vehicle.
