ABSTRACT:
A metal laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket includes a first metal plate with a base section, and a second metal plate situated above the base section of the first metal plate. The first plate includes a first hole to be sealed, and a flange situated above the base portion around the first hole to form a solid portion. The second plate has a second hole, and an inclined portion around the second hole. The diameter of the second hole is substantially the same as the diameter of the outer edge of the flange. When the first and second plates are assembled, the flange is located inside the second hole. When the gasket is tightened, the flange non-resiliently seals around the hole, and the inclined portion resiliently seals outside the flange.
