Cometic Gasket BMW M30B30V/M30B30/M30B32 .066in MLS Cylinder Head Gasket - 90mm Bore

This is a Cometic Gasket Multi-Layer Steel (MLS) cylinder head gasket designed for BMW M30B30V, M30B30, and M30B32 engines with a 90mm bore. It has an uncompressed thickness of .066 inches. MLS head gaskets are built for high-output engines and are ideal for sealing aluminum heads to cast iron blocks, or aluminum to aluminum, as they can handle the shearing forces between different metals. This gasket is a solid option for rebuilding the top end of your BMW, ensuring a strong seal without needing additional sealants.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .066 inches found on this particular gasket. The compressed operating thickness of this gasket is .036 inches, which is important to consider when setting up your engine's valve train.

This gasket fits a range of BMW models including the 533i, 633CSi, and 733i from the 1970s and 1980s, as well as earlier models like the 3.0CS and Bavaria. Ensure your engine and bore size match the specifications for a direct fit.
