Re : Oil Cooler It doesn't make any difference which way you connect the oil cooler because they will flow both ways. A pressure actuated control valve allows oil flow to the cooler and is situated above the oil filter.
Should have explained. i am putting a temp sensor in and need to know the inlet site so i can get an accurate temp.
don't know how accurate that will be? oil only flows to the oil cooler under high oil pressure ie when your gunning it etc or something like that
