so i recently got a 93 xj with a 4.0 5spd 4x4, and lately when i start the truck and its cold, for the first few minutes when im driving at partial throttle in 1st & 2nd gear from 1500 to 2200 rpms im getting a knocking sound, sounds like a rod knock but i thought a knock would stay consistant not come and go, i thought maybe someone could give me some ideas to check. The truck has excellent oil pressure and once its been running for 10 - 15 minutes the noise is gone completely til the motor cools down again...
