ABSTRACT:
The oil pan drain port adapter assembly for an engine flushing system includes a main adapter member and a plurality of interchangeable adapter members. Each of the interchangeable adapter members includes a first threaded cylindrical end portion for engaging and mating with a corresponding threaded portion in the oil pan drain port, an opposing end portion forming an annulus, and an interior lumen connecting the first threaded cylindrical end portion and the opposing end portion in fluid communication. The opposing end portion of each interchangeable adapter member is received in the inlet end of the main adapter member at a fixed angle of orientation. The annulus has a plurality of apertures extending through the annulus to permit fluid flow from the interchangeable adapter member to the inlet of the main adapter member. A set screw extends within and rides in the annulus of the interchangeable adapter member, preventing the interchangeable adapter member from being dislodged from the main adapter member.
