Cometic Oldsmobile LD9 Quad 4 .075in MLS Cylinder Head Gasket - 3.595in Bore - With EGR

If you're rebuilding the top end of your Oldsmobile LD9 Quad 4 engine, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice. It's specifically made to fit a range of vehicles like the Chevrolet Cavalier, Pontiac Sunfire, and Oldsmobile Alero, with a compressed operating thickness of 0.075 inches and a bore size of 3.595 inches. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block.

What makes this gasket stand out is its construction. It's built from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This advanced coating is designed to work well with different surface finishes and sealing environments, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block setups. The center layer is also stainless steel, and Cometic uses different thicknesses for this layer to meet various engine requirements.

This particular gasket includes provisions for EGR (Exhaust Gas Recirculation), so make sure that matches your engine's setup. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.
