A system for and method of separating oil from crankcase air is provided. The system includes replacing a standard shaft, such as a water pump shaft, with a breather shaft of the present invention and venting crankcase air through the breather shaft to an outside volume of air, such as in an air box. The breather shaft includes a centrifuge positioned within an interior volume of the crankcase and a first portion extending from the centrifuge through a wall of the crankcase. The centrifuge defines a plurality of inlet passageways extending from an outer surface of the centrifuge towards an interior area of the centrifuge. The first portion of the breather shaft defines a venting passageway extending from the interior area of the centrifuge to a vent opening at a distal end of the breather shaft.

The present invention is a dental evacuation tool for being placed in fluid communication with a dental vacuum. The tool comprises a suction head and an elongated tubular handle. The suction head includes a mirror surface, first and second upward-facing intake orifices adjacent the mirror surface, and an exit fluid pathway that is in fluid communication with the first and second upward-facing intake orifices. The elongated tubular handle includes a first end adapted to be in fluid communication with the vacuum and a second end in fluid communication with the exit fluid pathway. The first and second upward-facing intake orifices are positioned generally opposite each other about the mirror surface, are generally centered about a line that is generally perpendicular to the longitudinal axis of the handle, and open in generally the same direction faced by the mirror.
