Sometime back with about 80,000 miles, I heard what I thought was a rod knock after I lost oil pressure. Long story made short, the oil pressure turned out to be an intermittent oil pressure sensor, and the knock was the AC compressor clutch, but better to be safe than sorry when you see no oil pressure on the highway.
I pulled the pan and plasti-gauged the rods and mains. My crank looked good with no signs of wear, the rod bearings were showing signs of wear, and the mains were within tolerance and looked like new. I replaced the oil pump and rod bearing only. When you change your rod bearings, plasti gauge a new bearing and check your clearance, there are 0.001 over sized rod bearings available which will bring a worn crank back to tolerance.
I now have 230,000 miles on the Jeep and have a solid 35 psi at idle after a long drive on hot day in Florida.
