Check crankshaft end play. Sounds crazy but it happens all the time where u take the belt off and the knock goes away because the belt load all the way out on the end of the crank will cause it to walk back n fourth in the block and make a knock

Okay. Maybe the tension arm-bar. I've seen some click before.
