If you really want to know where your oil pressure goes use a pressure pot of oil to pressurize the oil gallerys before you put the pan on, then look where the leaks are, the bearings should drip, any missing plugs will make a big leak, and a steady stream out a bearing probably means too much clearance or a defect

I had to fix a Mercedes engine that the owner said had no oil pressure showing on the dash,that the gauge must be bad, it had 3 lbs at 2000 rpm on external gauge, it had been driven a month that way, I found 1/2 a bolt on top of the oil filter, upon removal of the pan 1/2 of the oil pump housing laying in the bottom,a windage tray bolt had been sucked in, no bearing damage, just a new oil pump
