Abstract
A plug assembly is provided including an elongated sleeve defining a longitudinal bore therethrough and including structure thereon for at least semi-permanent sealed securement through the drain bore of an oil pan. The plug assembly further includes a plug member defining an enlarged head and an elongated shank projecting lengthwise outwardly from one side of the head and removably telescopingly receivable in the longitudinal bore through the sleeve. Seal structure is carried by the shank and establishes a slidable fluid tight seal between the shank and the adjacent surfaces of the sleeve bore. The head of the plug member and the adjacent end of the sleeve include coacting structure releasably securing the plug member against outward displacement relative to the sleeve end and thus lengthwise retraction of the shank and the seal structure from the sleeve bore.
