Abstract: The gasket includes a gasket body which is made of a monolithic piece of an elastomeric material. The gasket body has an oil opening for allowing oil to pass between the timing chain tensioner and a cylinder head. The gasket body includes at least one outer engagement feature for directly engaging with an outer wall of the timing chain tensioner to hold the gasket body on the timing chain tensioner. The gasket body also includes at least one inner engagement feature for directly engaging with an inner wall of the timing chain tensioner to further hold the gasket body on the timing chain tensioner.

Abstract: An improved multi-layer gasket assembly is provided. The gasket assembly includes a plurality of metal gasket layers which have at least one set of axially aligned openings. The plurality of layers includes at least two functional layers, at least one distance layer and at least one stopper layer. Each of the functional layers has at least one embossment bead that is spaced radially from the openings, and the distance and stopper layers are sandwiched between the functional layers. At least one of the stopper and the distance layer has a polymeric coating applied to at least a portion of an exterior surface thereof, and the stopper and distance layers are laser welded together through the polymeric coating.

Abstract: A gasket assembly and methods of construction and assembly thereof are provided. The gasket assembly includes an elastically deformable, resilient carrier layer having an upper surface and a lower surface extending in planar, generally parallel relation with one another between an inner periphery and an outer periphery when in a disassembled state. At least one top layer is fixed to the upper surface proximate at least one of the inner periphery and the outer periphery. At least one bottom layer is fixed to the lower surface in radially spaced relation from the at least one top layer. The upper surface and the lower surface take on a non-planar, spring-biased shape upon compressing the gasket assembly between a pair of surfaces to an assembled state.
