ABSTRACT:
Mechanism for draining an engine oil filter cartridge when the space bene the cartride is otherwise obstructed. A special housing is threadably connected to the filter base in a non-obstructed location. A drain plug within this housing is manually unthreaded during a drain operation. A special boot in the mouth opening of the housing permits external actuation of the plug without undesired splash-out of oil through the mouth opening.
