My new to me burb did something funny. It dropped to 0 PSI when I got off the freeway. I think it's a fauls reading becuase the FI never shut down. I readsomewhere that if the FI sees 0 oil pressure that if kills the fuel pump. Anyway I want to hook up a mechanical oil pressure gage for a couple day's to verify the oil pressure. Where are the oil ports on this motor. Looks like the oil pressure gage sender is down on the front of the block on the passenger side. Most GM 350's in trucks had a port right up about the timming chain cover. Is there a nice easy one to get to on the 454 like that?
