Abstract

A process and apparatus for changing the oil in an engine and/or flushing and/or cleaning the moveable parts in the engine. The device includes an oil filter adapter adapted to be positioned in the oil filter boss, a remote oil filter mounting boss and inlet and outlet hoses connecting the two. The device is attached to the engine. Suitable pump-out and fill lines are connected to the device and can be releasably attached to an external pump device. When the device is employed to change oil, the external pump device is connected, and spent oil removed from the oil pan under suction force through the pump-out line. A measured amount of fresh oil is then introduced through pump-out line alone or through the pump-out line and the fill line and internal lube oil distribution system. Once accomplished, the external pump device can be uncoupled. When thorough cleaning is required, a suitable flushing fluid is introduced under pressure through the fill line and the internal oil distribution system after the spent oil is pumped out to scrub clean the internal passages and surfaces. The flushing fluid can be recirculated as desired to achieve thorough cleaning and, then, removed through the pump-out line.

3. The device of claim 2 wherein said external pump device comprises:

means for pumping fresh and spent oil;

at least one fluid conveying conduit in fluid communication with said pump means; and

a second quick connect coupling member on said fluid conveying conduit adapted to be matingly connected to said first quick connect coupling member on said oil conveying conduit line.

4. The device of claim 1 further comprising:

an oil filter adapter adapted to be sealingly connected to an engine oil filter mounting boss located on the internal combustion engine, said adapter having at least two openings, a first opening in fluid communication with an engine oil pump located in the oil pan and a second opening in fluid communication with an internal lube oil distribution passage system of the engine;

a remote oil filter mounting boss having first and second apertures, said mounting bracket positioned on the engine remote from said engine oil filter mounting boss;

an oil filter removably mounted on said remote oil filter mounting boss;

a first inlet hose connected to said first opening and said first aperture of said mounting bracket;

a second outlet hose connected to said second opening and said second aperture on said mounting bracket; and

a fill line connected to said second outlet hose said fill line having a coupling member attached at a remote end, said coupling member adapted to removably contact said external pump device.

5. A process for changing oil in an internal combustion engine having an oil pan with an associated drain opening and removable drain plug, equipped with a high speed oil change device, the device including:

a drain adapter having a body, a central throughbore with first and second outlets said throughbore extending through said body, a connecting bore in fluid communication with said central throughbore having a branch outlet, and means for sealingly retaining the drain plug in said first outlet of said connecting bore;

means for maintaining said second outlet in fluid communication with the drain opening;

an oil conveying conduit line connected to said branch outlet, said conduit having a first quick connect member at a remote end, said quick connect member adapted to removably contact an external pump device, fresh oil reservoir and spent oil reservoir, the process comprising the steps of;

connecting said oil conveying conduit line to said external pump device;

removing spent oil from the oil pan by applying a suitable suction force though said oil conveying conduit line on said spent oil, said suction force exerted by said external pump device; and

after spent oil is removed, introducing a measured amount of fresh oil through said oil conveying conduit line into the oil pan.

6. A process for changing oil in an internal combustion engine having an oil pan with an associated drain opening and removable drain plug, equipped with a high speed oil change device, the oil change device including:

a drain adapter having a body, a central throughbore with first and second outlets, said throughbore extending through said body, a connecting bore in fluid communication with said central throughbore having a branch outlet, and means for sealingly retaining a drain plug in a drain opening in an associated oil pan associated with the internal combustion engine in said first outlet of said connecting bore;

means for maintaining said second outlet in fluid communication with the drain opening;

an oil conveying conduit line connected to said branch outlet, said conduit having a first quick connect member at a remote end, said quick connect member adapted to removably contact an external pump device, fresh oil reservoir and spent oil reservoir;

an oil filter adapter adapted to be sealingly connected to an engine oil filter mounting boss located on the internal combustion engine, said adapter having at least two openings, a first opening in fluid communication with an engine oil pump located in the oil pan and a second opening in fluid communication with an internal lube oil distribution passage system of the engine;

the process comprising the steps of;

connecting said oil conveying conduit line and said fill line to said external pump device;

removing spent oil from the oil pan by applying a suitable suction force through said oil conveying conduit line on said spent oil contained in said oil pan, said suction force exerted by said external pump device;

after said spent oil is removed, introducing a measured amount of fresh oil into the engine through the fill line in communication with the internal lube oil distribution passage system and said oil conveying conduit line in fluid communication with said fluid conveying conduit, said fresh oil introduction under sufficient pressure to produce a spray pattern sufficient to permit contact between said fresh motor oil and moveable engine parts; and
