Cometic Toyota 1UZ-FE .045in MLS Cylinder Head Gasket - 92.5mm Bore - Without VVT-i - RHS

If you're rebuilding the top end of your 1990-2000 Lexus LS400, getting the cylinder head gaskets seated properly is key to a healthy engine. This Multi-Layer Steel (MLS) gasket from Cometic is built for the Toyota 1UZ-FE engine and is designed to handle the pressures of high-output applications without needing extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This particular gasket has a 92.5mm bore and is made for engines without VVT-i, specifically for the right-hand side (RHS) of the engine. When compressed, it measures 0.036 inches thick, but it's listed at a 0.045-inch thickness to account for variations in engine assembly.

This type of MLS gasket is a solid option for pairing aluminum heads with either aluminum or cast iron blocks, as it can manage the different expansion rates between those materials. It's a well-built component that helps ensure a reliable seal for your engine's combustion chambers.
