An interesting problem is starting to develop on my '01 Bullitt with 110k miles. Immediately after I start the engine in the morning the oil pressure gauge goes up to its normal position then the needle drops all the way down, appearing as if I've lost all oil pressure. The needle will stay down for a couple of seconds then pop back up to the normal position. It'll repeat this once or twice more before staying in the normal position. So far I've only seen this occur in the morning when I start the car up for the first time for the day.
Does this sound like a bad oil pressure sending unit, bad gauge, oil pump starting to go bad? Anyone else experience this before?
