Abstract
A molded thermoplastic valve stem oil deflector for an internal combustion engine comprises a two piece cup-shaped member having a skirt and a neck defined by two axially spaced radial flanges. The flanges have apertures therethrough defining a radially inwardly opening annulus for the acceptance of a conventional O-ring that seals on the valve stem and supports the oil deflector relative thereto.
