One embodiment may include a bushing (100, 300) and a seal member (102, 104, 200, 302). The bushing may be located in a cavity (56) of a stationary body (46) of an engine breathing system valve (12). The bushing may be located around a moveable stem (48) of the engine breathing system valve in order to facilitate movement of the valve. The seal member may be located in the cavity and around the stem. The seal member may substantially prevent fluid-flow between an outer diametrical surface (76) of the stem and a confronting inner diametrical surface (120, 128, 202, 308) of the seal member.
