Abstract

A gasket includes at least one gasket layer. The gasket layer has a push rod or cam timing chain opening formed therein. A clip is secured to the gasket layer and positioned within the push rod or timing chain opening. The clip selectively receives and positions an oil drain tube within the push rod or timing chain opening.

Claims (27)

1. A cylinder head gasket comprising:

at least one gasket layer;

wherein said gasket layer includes a push rod opening formed therein; and

at least one clip secured to said gasket layer and positioned within said push rod opening, said clip selectively receiving and positioning an oil drain tube within said push rod opening.

2. The cylinder head gasket of claim 1 , wherein said clip includes a base portion, a body portion and an opening formed in said body portion.

3. The cylinder head gasket of claim 2 , further including an upwardly extending flange at least partially surrounding said opening.

4. The cylinder head gasket of claim 2 , further including at least one slit that is in communication with said opening.

5. The cylinder head gasket of claim 4 , wherein said slit extends from an outside periphery of said body portion to said opening.

6. The cylinder head gasket of claim 1 , further including an integral protrusion that extends from an edge of said push rod opening, said clip being secured to said protrusion.

7. The cylinder head gasket of claim 6 , wherein said clip is secured to said protrusion by welding.

8. The cylinder head gasket to claim 6 , wherein said clip is secured to said protrusion by riveting.

9. The cylinder head gasket to claim 6 , wherein said clip is secured to said protrusion by form-lock.

10. The cylinder head gasket of claim 1 , wherein said gasket includes multiple gasket layers.

11. The cylinder head gasket of claim 10 , wherein said gasket is a multiple-layered steel gasket.

12. The cylinder head gasket of claim 1 , wherein said clip is located between a pair of bridges that span said push rod opening.

13. The cylinder head gasket of claim 12 , wherein said bridges include a locator hole for receiving a push rod therethrough.

14. A cylinder head gasket comprising:

at least one gasket layer;

wherein said gasket layer includes a push rod opening formed therein; and

at least one protrusion integrally formed with said gasket layer, said protrusion extending away from a periphery of said gasket and within said push rod opening, said protrusion including an opening formed therein for selectively receiving and positioning an oil drain tube within said push rod opening.

15. The cylinder head gasket of claim 14 , further including at least one slit extending radially from said opening.

16. The cylinder head gasket of claim 14 , wherein said protrusion is located between a pair of bridges that span said push rod opening.

17. A cylinder head gasket, comprising:

at least one gasket layer;

wherein said gasket layer includes a timing chain opening formed therein; and

at least one clip secured to said gasket layer and positioned within said timing chain opening, said clip selectively receiving and positioning an oil drain tube within said timing chain opening.

18. The cylinder head gasket of claim 17 , further including an integral protrusion that extends from an edge of said timing chain opening, said clip being secured to said protrusion.
