Cometic Toyota 4AG GE 83mm .045 inch MLS Head Gasket Guanaja Dive Sites Clark's Cay Guanaja. Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0. 045". Cometic MLS (Multi Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements Requires less clamp load creating less bore distortion Conforms load distribution across the sealing area Embossed Outer Layers Coated w Viton This Part Fits: Year Make Model Submodel 1985 1988 Toyota Corolla DLX 1988 Toyota Corolla DLX All Trac 1987 1988 Toyota Corolla FX 1987 1988 Toyota Corolla FX16 1987 1988 Toyota Corolla FX16 GTS 1988 1991 Toyota Corolla GTS 1985 1988 Toyota Corolla LE 1985 1986 Toyota Corolla LE Limited 1985 1987 Toyota Corolla Sport DLX 1985 1987 Toyota Corolla Sport GTS 1985 1987 Toyota Corolla Sport SR5 1988 Toyota Corolla SR5 1988 Toyota Corolla SR5 All Trac 1985 1989 Toyota MR2 GT 1988 1989 Toyota MR2 Super Charged
