Annoying ticking

I seem to have an annoying ticking sound lately. Truck runs fine and I am using rotella T6 5w40 and revx. It seems like it's drivers side. I am not sure if it's just a loud injector or what. Any suggestions on where to start my diagnosis? The tick follows with RPM and is most audible at low RPMs.

you could try unplugging the injectors one at at time. check for soot around your exhaust manifold too. any exhaust leak at one primary would cause that too

What's the process for unplugging and plugging in the injectors? My FICM is also reading 48.5 to 49V at all times so it should be fine.
