Cometic Oldsmobile LD9 Quad 4 .027in MLS Cylinder Head Gasket - 3.595in Bore - With EGR

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket for Oldsmobile LD9 Quad 4 engines. It has a compressed thickness of .027 inches and a bore size of 3.595 inches, and it includes provisions for EGR. This gasket is built with multiple layers of stainless steel, with the outer layers coated in Viton rubber, a heat-resistant material designed to handle harsh sealing environments and different surface finishes. The multi-layer design offers increased strength and resistance to corrosion, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. Because it's an MLS gasket, it doesn't require any additional sealants.

This gasket is a solid option for rebuilding or repairing the top end of your engine. The Viton coating on the embossed outer layers helps ensure a strong seal against combustion pressures and fluids, even with the stresses that can occur between dissimilar metals like aluminum heads and iron blocks. The stainless steel construction provides rebound strength and corrosion resistance, which are important for long-term sealing performance in high-output applications.

This gasket fits a range of GM vehicles, including models like the Chevrolet Cavalier, Pontiac Sunfire, and Oldsmobile Alero. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures.
