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.

Claims (13)

1. A manifold gasket assembly for an internal combustion engine, comprising:

a carrier body adapted to be clamped between a cylinder head and a manifold of the engine, said carrier body having at least one media-conveying opening;

elastically resilient sealing material disposed on said carrier body in surrounding relation to said at least one opening operative to form a fluid-tight seal about said at least one opening when said carrier body is clamped between the cylinder head and the manifold;

at least one push rod guide formed from a material different than that of said carrier body mounted on and projecting from said carrier body in position to provide a guide surface for a pushrod during installation of the pushrod in the engine; and

a connecting web of said elastically resilient sealing material extending between said at least one pushrod guide and a ring of said elastically resilient sealing material extending about an adjacent said at least one opening.

2. The assembly of claim 1 , wherein said at least one pushrod guide is fabricated of said elastically resilient sealing material.

3. The assembly of claim 2 , wherein said at least one pushrod guide has a generally cylindrical pin configuration projecting from said carrier body.

4. The assembly of claim 2 , wherein said elastically resilient sealing material comprises a rubber material.

5. The assembly of claim 1 wherein said connecting web extends across a surface of said carrier body.

6. The assembly of claim 1 wherein said carrier body is fabricated of metal and said at least one pushrod guide is fabricated of a rubber material.

7. The assembly of claim 1 wherein said carrier body is fabricated of metal and said at least one pushrod guide is fabricated of the same material as that of the elastically resilient sealing material.

8. The assembly of claim 7 , wherein said pushrod guide is molded to said carrier body.

9. The assembly of claim 1 , wherein said gasket body has a plurality of said openings and a plurality of said pushrod guides.
