How bad are these bearings?

I did check the wrist pin while the connecting rod was unhooked from the crank. There did not seem to be any slop, but the piston rotated in the bore pretty easily so it was hard to check in every direction.

Bottom one has obvious wear in the middle. How did the journals look?

It's usually the top one that wears first with all the pressure on it on the power stroke...I'd be looking for an oil problem on #8

I was thinking about your problem and was going to ask you if it was a diesel. I am not familiar with the ford indirect injection but think this is ware might lay. Google (2000 7.3 idling possible injector knock) there are people complaining of the same problem.

I haven't ruled out injector knock completely, but I did switch around injectors to see if it followed one of them and it stayed with the cylinder. It is a fully mechanical system so there is a chance that the injection pump could be going bad but that is an expensive part to swap without much evidence.
