An assembly for installation on an internal combustion engine for facilitating engine cleaning and oil change and method for using the same which includes an oil filter mounting adapter interposed between the multichannel oil filter unit and the engine and a fluid egress assembly mounted in the drain opening of the oil pan. The oil filter mounting adapter is configured to be readily mountable in engine compartments having significant space constraints. The oil filter mounting adapter is composed of a sandwich adapter and a fluid coupling assembly. The fluid coupling assembly includes a quick connect nipple which is releasably matingly engageable with mating fitting on an external fluid supply source. The fluid egress fitting also includes a quick connect nipple releasably matingly engageable with a mating fitting on a fluid removal hose or conduit.

[ What is claimed is:] [1.] An oil filter mounting adapter connectable with an internal lube oil passage system located in an engine block of an internal combustion engine, the oil filter mounting adapter comprising:a sandwich adapter having a first face having an essentially flat planar surface adapted to sealingly contact an oil filter mounting boss and communicate there through with the internal lube oil passage system in the internal combustion engine, the oil filter mounting boss having an oil entry orifice and at least one oil exit orifice defined in the engine block, the oil entry orifice having an inner diameter, said oil filter sandwich adapter having a second face adapted to sealingly contact an associated oil filter unit, and an outer wall member defining an outer perimeter of said sandwich adapter disposed between said first and said second faces and perpendicularly attached thereto, said sandwich adapter having at least one fluid transfer opening defined in said flat first face in fluid communication with the internal lube oil passage system of the internal combustion engine, at least one oil collection chamber proximate to said oil filter unit, at least one fluid exit opening proximate to said oil filter unit, a central through bore extending laterally through said sandwich adapter from said first face to said second face, said fluid transfer opening, oil collection chamber and fluid exit opening forming at least one fluid transfer channel extending laterally through said oil collection chamber to said engine oil exit opening, and an aperture located in said outer wall member, said aperture defining an associated longitudinal fluid transfer channel, said longitudinal fluid transfer channel terminating in fluid communication with said at least one lateral fluid transfer channel defined in said sandwich adapter, the sandwich adapter further having a nipple extension integrally formed with the sandwich adapter positioned coaxially with said central through bore and extending outward from said second face, said nipple extension comprising means for releasable engagement with a central aperture located in said associated oil filter unit, wherein said associated oil filter unit is engaged in releasable sealing attachment with said second face of said sandwich adapter;a fluid coupling assembly sealingly positionable in said associated outer wall aperture,means for connecting said sandwich adapter to said oil filter mounting boss;wherein said central through bore defined in said sandwich adapter has a first section in fluid communication with said oil entry orifice, the first section having an inner diameter, the central through bore further having an intermediate section in fluid communication with said first section and a second section in fluid communication with the intermediate section and extending through said nipple extension, said second section having an inner diameter less than said diameter of said first section, said intermediate section having a tapered surface connecting said first section and said second section.
