I recently installed a new crank, rod, and main bearings, timing set, oil pump on my '87 XJ. About 200 miles before doing this I replaced the head, and lifters. The motor is basically new except for the pistons, rings, cam, and cam bearings. I know it sounds stupid but I actually replaced more than I could afford as it was.. and I couldn't afford pistons.. and having them put on the rods..
Anyways.. I still have some thumping in the motor.. I can hear it echo off walls.. and other cars.. my oil pressure is stellar.. and it runs really well.. it occasionally doesn't idle great. However, I'm getting 20mpg hwy. So its running pretty well.
I can only assume that the noise I'm hearing is piston slap.. The pistons have 260k miles on them so I don't blame them. The jeep never smokes, and doesn't use oil.. that's another reason why i left well enough alone... or what I thought was well enough.
My question is.. if the noise is pretty moderate.. any guesses on how long I can go before it gets much louder.. or a skirt breaks off?
