The sound was on the left side if your standing in front of the engine bay did check the timing cover sound was on the same side but as i went down the rocker cover toward the back it got quieter .the timing was done 3 months ago got the knock 3_4 weeks later then was put in the shed until now as we moved house
I showed my boos at work the video i took and he also reckons its not engine but some thing like timing i told him i had it. Replaced by a shop we suply parts to every day he was not happy so shouldi pull the timing cover off the engine and see if there is a failed part if so is there a easy way to do it with out striping the engine right down take in account this is my first jeep not the japan imports im use to
Attached service manual print for the timing cover removal. You should be able to remove it with the engine in place. Maybe radiator has to be removed to create enough space to get to the cover. Its not just a simple cover to be removed, it requires draining the cooling system and removing the crankshaft vibration damper, which requires a puller. Not impossible to do, but for sure not a first time job.
