A multi-layer engine gasket is provided for resisting scoring, scratching and abrasive-erosion. The gasket assembly includes a flat-elongated core or base, a sheet of composite gasket material on each face of the base, armor to seal the combustion chambers, and an exterior layer of erosion resistant material applied to the facing sheets along one or more of the two shorter ends of the gasket assembly. Apertures are provided for the combustion chambers, the water and fluid passageways and the head bolts. The abrasive-erosion resistant layer is a mixture of molybdenum disulfide and graphite, preferably with a minor amount of a binder and adhesion promoter. The abrasive-erosion resistant layer is selectively applied to the end zones of the gasket assembly.
