ABSTRACT:
A cylinder head gasket prepared by a method of the invention is installed between a cylinder head and a cylinder block. In the method, a plate is prepared at first to have at least one hole smaller than a hole of the engine to be sealed. The first plate is bent around the first hole so that the first plate is provided with a curved portion defining a hole corresponding to the hole of the engine, a flange extending away from the curved portion, and a space around the curved portion. The curved portion is compressed to eliminate the space to thereby form a solid portion by the flange and an annular portion. A second plate having a hole larger than the flange is prepared and is assembled with the first plate. The second plate is located at a side opposite to the flange of the first plate. The second plate does not laminate the flange of the first plate.
