ABSTRACT:
A crankcase drain valve assembly for replacing the standard oil drain plug commonly used for draining used oil from the crankcases of most internal combustion engines. The assembly includes a valve housing for mounting in the drain opening of the crankcase formed with a central passage therethrough and a transversely extending valve opening intersecting the central passage. A valve member is pivotally attached to the valve body and is formed to move in and out of sealing engagement with the central passage. A lever attached to the valve member permits opening and closing of the valve member without any special tools. The valve member is held in the closed position by rotating a lever until a boss on the lever arm is received in a detent in the valve housing.
