Oil Pressure Problem Solved

I have a 1997 Jeep Wrangler 4 cyl. Running cold everything was fine. Oil pressure ran at 40 lbs. After warming up the oil pressure still ran at 40lbs on the road but when stopped it would drop below 20lbs and at times would bottom out and the engine light would come on. I feared the worst. After reading some other forums I took a stab in the dark and purchased a new oil pressure sending unit from a dealer. I don't buy electrical parts from the franchises. Now my oil pressure runs at 50lbs on the highway and never drops below 20lbs stopped no matter how warm she is....This might be the best $60.00 I ever spent...........I hope this information is helpful to someone else. It was a blessing for me......................Marko

For real...............I have now had to purchase all three................

I don't know if that was really so much of a shot in the dark, its fairly common on Jeeps. Also crank position sensors. And exhaust manifolds.

This could be true..........Ask me how I know?
