First thing to do is remove the oil pressure sender. It's way in the back by
the distributor. Hook a regular mechanical gauge to the port where the
sender was and see what's really happening. The oil pressure sender could be
the problem. My 92 360 is on it's third. The first replacement I bought
started leaking after about a year.
