In the shortest terms I can think of, you are opening up the oiling system so that you can place a filter or cooler or both (most often) 'into' the normal flow of the oiling system. The new components are placed directly between the oil pump's output and the path to the engine's oiled components.
Perhaps it gets its name from the fact that if you incorporate a cooler, the 'full flow' of oil passes through it - unlike in a standard case where the oil control valves may bypass the cooler . . . just a thought. Perhaps because you are directing the 'full flow' of oil.
Ok, that makes a lot of sense. The motor (lightly used) that I'm looking into has a remote oil filter. I'm not sure, but I was thinking about adding one on, since it is a larger motor, 2165, i was thinking that a remote oil cooler would help to keep running cool on longer trips...
So it doesn't have anything necessarily to do with the machining of the case?
