Abstract:
An engine is provided with a block forming a cylinder, a head, and a gasket positioned between the block and the head. The gasket has first and second outer layers and a distance layer positioned therebetween. The first layer defines a first aperture and a bead surrounding the cylinder. The distance layer defines a second aperture concentrically arranged between the first aperture and the bead. The gasket has a stopper layer extending inwardly from the distance layer to a circular stopper element positioned adjacent to and aligned with the first aperture. A method of sealing an engine includes compressing a gasket between a block and a head to form a primary seal at a first interface and a secondary seal at a second interface between first and second outer layers and an intermediate layer, the first interface being positioned between the second interface and a bead surrounding a cylinder.
