Abstract: A manifold gasket assembly includes a steel carrier fabricated with a plurality of air intake openings. Rubber material is molded to the carrier body to provide a seal about the openings when the gasket assembly is clamped between a cylinder head and intake manifold. Pushrod guides are provided on the carrier body and are fabricated of a material different than that of the carrier body, namely the same material as that used to form the elastomeric sealing beads.

Abstract: The gasket assembly includes a gasket layer and a separately formed shim layer. The shim layer and gasket layer are formed with at least one media-conveying opening that correspond to media-conveying passages communicating between first and second members to be clamped together and sealed by the gasket at the joint between members. The shim layer has an adhesive layer applied to its back surface 36 to enable the shim layer 14 to be adhered to original clamping face of the one of the first or second members in order to build up the surface or to cover up damage on the clamping face that could impair proper sealing with the gasket.

Abstract: A head gasket assembly for an engine with minimal space between adjacent cylinder bores. Armoring including a bridge between adjacent combustion openings is provided with the legs of the combustion openings enclosing wire rings and being welded to each other in the zone of adjacency. The wires are stabilized and maintained in permanent close adjacency.

Abstract: A gauge and method for reestablishing the designed relationships between the block, heads and intake manifold of a V-engine after it has been disassembled for refinishing. The angular relationship between the surfaces of the heads is ascertained to determine if they are correctly oriented prior to final assembly with the intake manifold.

Abstract: An automotive head gasket assembly and shim for installation between the head and block of an engine is disclosed. The head gasket includes a main body of a first thickness having a central core and compressible composite facing layers laminated to the surface of the core. The main body defines a plurality of combustion openings. A fire ring is disposed and secured in each combustion opening. Each of the fire rings includes a generally U-shaped armor having a pair of legs overlying and underlying the main body adjacent a combustion opening and a central body connecting the legs and ensheathing a wire ring for providing a combustion seal. A shim is temporarily disposed on the gasket on one of the facing layers. The shim surrounds each of the combustion openings and defines openings thereat of a size greater than the size of the wire ring so that the wire ring is disposed to lie within the opening.

Abstract: A method of sealing a high performance internal combustion engine with a head gasket having a fire ring comprising providing a groove in the head or block generally concentric with each said combustion opening, each groove having a land area and a generally vertical wall, and positioning the gasket on the block so that when the head is torqued down, each groove receives a fire ring and compresses the wire ring thereof to provide a primary seal therewith at the land area, the wall engages the armor of the fire ring to form a secondary seal, and the head and block clamping surfaces engages the armor to clamp the armor. The head gasket has a main body of a first thickness and defines a plurality of combustion openings. A fire ring is disposed and secured in each combustion opening, each fire ring comprising an armor ensheathing a wire ring for providing a combustion seal. The armor is of a second thickness substantially greater than the first thickness. The armor and main body may be intergrally formed.

Abstract: A head gasket assembly for closely adjacent cylinder bores and method of making the assembly. In the zone of adjacency of the combustion openings in the gasket assembly, part of the gasket body material is absent. Adjacent armoring is joined to form a bridge at the zone of adjacency. The armoring has wires which are substantially greater in thickness than the gasket body material. When the gasket assembly is pre-compressed and compressed in use, the wires in the zone of adjacency are deformed into sealing engagement with each other.

Abstract: A method of making a composite gasket. A composite gasket is formed from an annular coiled strip of heat-resistant core material having a metallic tanged core and a facing layer, as of a mica-based material, integrated with the strip. The coil is placed in a first die and axially compressed under a relatively low pressure into a preform having a plurality of crevices in its face. The preform and a temperature-resistant sealing material, such as expanded graphite, are placed in a second die and the graphite and preform are axially compressed under high pressure to integrate the sealing material with the preform and to mechanically interlock the sealing material with crevices in the surface of the core material. The preform and sealing material are substantially deformed during the second axial compression to provide an improved composite gasket.
