ABSTRACT:
In an internal combustion engine having an assembly consisting of a seal gasket for the valve stem and a spring support cap, the gasket is mounted on the valve guide to form a seal against the valve stem and the spring support cap is mounted externally of the gasket and has an outwardly-extending flange that rests directly on the engine cylinder head. The lower end of the gasket has an outwardly extending flange for retention by the support cap, the latter having a stepped cross section to enable it to be centered on the exterior surfaces of the gasket with an interference fit. The valve spring bears on the flange of the support cap.
