Nissan Repair: oil pressure, oil change intervals, nissan maxima

Question
I have a 1990 nissan maxima that looses oil pressure after driving for 10 min. the light comes on and the lifters start clicking. I turn the car off wait 5 min. and i have pressure again for 10 min. what can cause this? could it be the pressure regulator?

Answer
HI John -

I am assuming that the oil level is OK in your engine.

Other than that, it looks like the oil sump screen is clogged, or the oil pump is bad. What are the oil change intervals you have for this car? If an oil change is due, perhaps you might try to add and engine flush to the crankcase before changing the oil.

Hope this helps -
