Claim Text:
1. A cylinder head gasket establishing a fluid tight seal between a cylinder head and an engine block of an internal combustion engine, comprising: a gasket layer which presents at least one inner periphery that surrounds at least one opening and said gasket layer having a first thickness adjacent said inner periphery; a combustion seal positioned in said at least one opening and extending circumferentially around an axis between ends that are joined together and said combustion seal being joined with said inner periphery if said gasket layer; said combustion seal having a height in a direction parallel to said axis and said height being greater than said first thickness of said gasket layer; said combustion seal which is substantially generally C-shaped in cross-section and is resiliently flexible for maintaining fluid tight seals with the cylinder head and the engine block during operation of the engine; wherein after full compression said C-shaped combustion seal presents a pocket which faces away from said inner periphery of said at least one gasket layer for receiving combustion gasses during use to improve the fluid tight seals established with the cylinder head and the engine block, and wherein the combustion seal is separate and completely spaced from the gasket layer.
