The exact number isn't as important as how much the pressure gauge fluctuates. Watch the gauge when the engine is first started. It should go up somewhere near the middle. That's the point at which the pressure bypass engages.
Then watch the oil pressure after the engine warms up. If the oil pressure drops significantly AT AN IDLE when the engine is warm, you have worn main and/or rod bearings... but WORN doesn't mean WORN OUT.
If the engine is still able to maintain oil pressure, even though it drops a little when warm, you can raise the oil pressure by changing to a heavier (thicker) grade oil. If you've been using 5W15, change to 10W30 or even 15W40. You'll be surprised at how much of a difference that can make.
