Abstract
An extension tube for an internal combustion engine oil fill tube comprises an elongate bent cylindrical member having one threaded end adapted to engage within a threaded port in a valve cover. The tube includes a protruding nub thereon which is positioned to coact with a cavity between segmented threads in the port to produce a detent between the tube and the port when the tube is threaded into the port to a desired relative rotational orientation, for maintaining such orientation. The tube further includes a peripheral flange which compresses a high swell material seal member placed therebeneath against an area disposed about the port to ensure integrity of the engagement.
