reversing oil cooler connections
Discussion
i have an old 1980's BMW with an original-fit horizontal oil-cooler slung under the radiator.
2 pipes run back to the oil-filter housing on the side of the engine-block.
i want to rotate the filter-housing 90 deg. so the filter is vertical instead of horizontal,this is to stop the oil draining from the filter overnight.
with the housing in its new position one of the lines doesn't quite reach its home on the housing,but swapping the 2 lines over so the inlet one becomes the outlet gets round this.
this means the oil will now flow from the top of the cooler to the bottom rather than from the present bottom up to the top,- bottom-to-top apparently being the ideal direction.
anyone know if the cooler will still operate as intended in the reverse direction,or is this a no-go?

that's good to know thanks.
the problem with my filter is that when its in its original horizontal position,the oil drains out of it overnight,even tho it's a decent Mann filter with the usual anti-drain valve,this gives a 2-3 sec. delay in oil-pressure on starting from cold. 3 filters have been tried-all have this same problem.
from what iv'e read it seems likely there will be no probs reversing the flow-getting rid of air-bubbles is the reason behind the oil flowing bottom-to-top thru the cooler apparently.
