ABSTRACT:
A metal laminate gasket of the invention is used for an internal combustion engine. The gasket includes a main portion formed of at least two outer metal plates extending substantially throughout an entire area of the engine, a device for defining a first hole corresponding to a hole of the engine, and a coating applied onto a part of the defining device and one of the outer surfaces of the metal plates. The defining device are attached to the outer metal plates and has a plurality of dents near the first hole to surround the same. The coating is filled in the dents to cover a substantial area of the outer surface. Therefore, the coating does not substantially flow to thereby improve sealing around the first hole.
