Richard - My "before" oil pressure readings were a good constant 60 PSI (judging by the dashboard guage), but once the oil was very hot after about 15 minutes of driving (say), then when the car was idling, the oil pressure dropped to 30-40 PSI.
Ouch, I would say that is a bit on the low side for these engines. Good chance you've caught it before the engine went pop. Mine went with 65k on the clock!
Mine is 50 at tick over, 60 above 2000rmp hot or cold (including ten mins in a traffic jam on a hot day). Only drops a very little with 6 month old oil.
Nice one.
