Abstract
A power tool having a rotary implement driven by a four-cycle engine. The engine crankcase is through a passageway which extends through a camshaft to a valve chamber. The rotating shaft member inhibits the escape of lubricating oil when the engine is running while permitting a lubricating oil mist to circulate through the engine.
