if i remember right it said 120lb/ft, 160nm, it just sounds much?

i blew air in the hole where the arrow points, i know its the wrong direction for the oil to go but it was just for comparison. one of my lids where airtight and the other leaked a little from the other hole the arrow points out of. i figured there should be a spring/plug where i marked that shuts off oilflow to the jets on idle to maintain oilpressure for the rest of the engine. if so it should stay shut at low pressures as in my test and open at about maybe 2bar. im i totally wrong here in my thinking?
