About this part

Product Details

If you're rebuilding the top end of your 1999-2003 Toyota Sienna, a solid cylinder head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of modern engines, ensuring a strong seal between your cylinder head and engine block without needing any extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures and various sealing conditions. The center layer is stainless steel and can be varied in thickness to achieve precise compression ratios; this particular gasket has a compressed thickness of 0.051 inches and an 84mm bore, making it a good fit for specific Peugeot XU engine variants found in some Toyotas. This construction is ideal whether you have aluminum heads and an aluminum block, or aluminum heads and a cast iron block, as it can manage the different expansion rates between those materials.
