My oil pressure gauge is erratic and at low rpm drops to below zero and shows good pressure at highway speeds of 50 mph or better. the engine sounds fine and does not show excessive heat. The oil level is in the safe zone of the dipstick. I would like to try replacing the oil pressure sending unit but I am unable to find where it is on the block or how to get to it.
