Abstract: An air accelerating system includes a housing that has a bore extending through top and bottom ends of the housing. A mounting collar mounted on the bottom end fluidly couples the housing to an oil fill hole of a valve cover. An axle mounted in the bore has a plurality of main blades mounted thereon which are rotated when the axle is rotated to exhaust air from the bottom end to blow oil out of engine valves and into an oil pan of an engine. A drive mount mounted to the top end has at least one vent aperture extending therethrough that is in fluid communication with the bore. A drive spindle rotatably mounted to the drive mount is engaged with the axle and engageable with a drill. The drill rotates the axle to draw air into the vent aperture and expel it outwardly of the bottom end.
