Oil pressure drops
I had my engine torn down rebuilt oil pump
replaced drove 1000 miles it happened again.
What can it be?
faulty gauge if the gauge works like a dummy switch, or theres a leak somewere
I would install a manual gauge on it just to verify that you have an oil pressure problem and not just a sender or gauge problem.
