A multilayer metal gasket has a pair of outer active layers separated by an intermediate layer. The outer active layers are formed with at least one pair of aligned apertures and sealing beads surrounding the apertures in radially outwardly spaced relation thereto presenting laterally opposed sealing surfaces of the active layers of predetermined spacing or thickness when the gasket is in a compressed free state. The intermediate layer extends radially inwardly beyond the apertures and is provided with a cold formed stopper portion having a thickness greater than the combined material thicknesses of the intermediate layer and outer active layers but less than the thickness of the sealing beads. The stopper portion is cold formed under a compressive load exceeding the compressive load required to deform the sealing beads beyond their elastic limit, thereby preventing irreversible damage to the sealing beads. The stopper portion presents opposing sealing surfaces which, when the gasket is clamped between two members having a passage to be sealed, serves as a primary seal or fire dam, shielding the sealing beads of the outer active layers from direct exposure to the heat of any fluid in the passage, such as hot exhaust gases of an internal combustion engine.

A method of modifying a combustion seal of a diesel engine fitted with a cylinder liner having an annular top sealing ridge which is damaged or mispositioned so as to interrupt the combustion seal is provided. The method includes exposing the sealing ridge and, without removing the liner from the engine, clamping and plastically deforming a combustion seal shim against the sealing ridge to perfect the combustion seal.

An independent electrical moduledistributes an electrical signal to the terminalsof a fuel injector device in an engine. The modulecomprises a self-supporting plastic lead framewith copper ribbonsdisposed on the plastic frame. Pluralities of terminal connectorsare separate from and movable relative to the framefor being connected to the terminals. The ribbonscontinue in a free and self-sustaining support portionsbetween the frameand the terminal connectorsand are bendable for allowing movement of the connectorsrelative to the frame. Each of the connectorsincludes a polymeric body defining a pair of the socketswith an electrical contactin each of the socketsand a pair of the bendable support portionspaired with the contactsin each connector

A multi-part vibration isolating fastener assembly includes a bolt having a threaded shank and a head about which a sleeve and resilient grommet are disposed. A cup washer is disposed about and captured axially on the grommet to provide a unitized assembly. The integrated cup washer defines a self-contained cup-shaped socket to provide proper support and containment for the grommet in applications where the usual cup-shaped grommet wall is lacking in the components to be assembled, such as a valve cover, and cylinder head.
