ABSTRACT:
A metal laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket comprises a first metal plate, a second metal plate situated under the first metal plate, and a thin graphite layer attached to the second plate to face outwardly. The first plate includes a curved portion to define a first hole corresponding to the hole of the engine, and a flange around the first hole. The second plate has a second hole larger than the flange, so that when the first and second plates are assembled, the second plate does not pile the flange. The graphite layer fills dents or small scratches on an engine part when the gasket is installed in the engine.
