Yesturday on my drive home from work I blew the hose which can be seen in the picture on my 92 XJ. After the engine cooled I got the coolant cleaned up and replaced the hose. This morning on my drive back to work I noticed my oil pressure guage was really low compared to normal. Prior to the hose blowing it was always at 40. Now while giving it throttle it is at 40 and drops to 20 when I let off.

Is this normal?

 

could just be the sensor going bad, pretty common problem. Usually the start reading low, then high, then bouncing all over the place before just dieing

 

sounds normal to me, More throttle= more pressure/flow Less throttle=less pressure/flow

 

Its possible the the wiring to the sensor has antifreeze in/on it. I would get a mechanical gauge just to be 100% sure...Tj
