oil preasure guage

i have a 97 jeep cherokee country with a 4.0 inline 6 with alil over 235,000 original miles on the motor and i have been noticing the oil pressure would drop to 0 and when it goes up after driving it for a bit it will either be at 10 or 20 psi. i have replaced the valve cover gasket once and ive replaced the oil pressure sensor twice im on sensor three which is like a month old and its still doing it. when the gauge is at 0 nothing is happening to the motor it still drives fine. i dont know if this would effect it but the exhaust manifold is cracked at the collector which i plan on replacing soon once i order one. im gonna get a pressure gauge test kit and look up the pressure spec to see if the sensor is bad again or something.
if anyone has any other ideas that i can try that would be much appreciated

I'd put a known good mechanical gauge on it and see what the readings are. What grade oil are you running? With that many miles on the car, I would go up to a heavier grade.

When I see the price of OEM I think aftermarket.

I am betting your bearings are getting worn. I would test with a mechanical gauge with your normal oil. But you should probably switch to 20w50. Its thicker to help take up the most likely now out of tolerance bearings. It might buy you time until you can rebuild.
