Chasing an oil leak from the top of engine I replace all the common things but when I replaced the crankcase breather hose (on top) I blew through the hose just to see if it was clear I got a spurt of oil and air flowing out of the oil cooler hole on the top right. As I blow harder with air pressure the air keeps flowing out the oil cooler supply hole as hard as the air going in????? Doesn't seem right to me I also have low oil pressure at idle any ideas??
