Knocking Noise

I was doing a little maint. on the stroker today and noticed a knocking noise from the passenger side of the engine. This is the first time I have ever heard it. I know that the 7.3 is loud and noisy but this don't sound like it normally does. It almost sounds like a lifter or something. The truck has 193,000 miles on it. I am new to the mechanics of the diesel engine and haven't torn into one before, so I am comparing the noise to a gas motor. I don't want to sound dumb but was wondering if it could be a lifter, fuel injector, or ?. If I take it to a good reputable shop should they be able to diagnose the sound or is it a shot in the dark. If it is a lifter is it hard to replace? Is there any tests that I can run to help or any suggestions on how to go about and get it checked out?

Thank You all for your time and any help you can give.

Is it only at idle, only under load, or all of the time?

X2 on the rocker. So I have heard. I would suggest removing the VC and inspecting.

It is most noticable at idle. But you still can here it at higher rpms.
