Hey guys I have a 99 cherokee with 225k miles and recently started hearing a knock from the bottom end. It started right after replacing RMS and oil pan unless I just didn't hear it before. Knock is constant at all Temps. Unplugged all injectors and noise stays the same. It increases with rpm until a certain point and fades off. Used a screwdriver and definitely sounds like it's more pronounced from the oil pan. Anything I can do or suggestions? I literally just put 4 new tires control arms and front suspension along with a tune up and insured and registered after being worked on for 3 months so kinda disapointed.

 

Is it a heavy sharp sound or more like a thud?How loud? And what do you mean by constant; does it sound like it’s happening every revolution?
