Injector knocking?
I have to post this since I just noticed today. I have a knocking noise coming from the passengers bank. Not sure which one, but I can hear it mostly from inside the cab when idling. My truck has low miles, almost at 100k. The previous owner treated her with care, but towed a lot, and I mean A LOT. Not sure how much strain that'll put on injectors, but I've also noticed how my mpg are not what I was getting when I first bought the truck. I bought remans just in case. Also, how long do glow plugs continue to operate after starting the truck? Thanks in advance.

If one is loose then the heat of combustion most likely has torched it. If you find a very loose one you should prob pull it and check it out.

Easiest way to tell if you have an injector issue is to do a buzz test if you have the capability.
Start test, listen under the hood.
Check the sheet for the buzz order.
You'll know if you got an issue when you got one that buzzes really really odd.

Buzz test only checks the IDM, wiring, Solenoid, etc, and does nothing to indicate issues with the oil or fuel sides. More diagnosis is needed to help narrow down.
If there is one loose, you can knock them all on top with a mallet then check torque of the hold-down bolt. If you find one (or more?) that take substantial turns of the wrench to tighten, then that injector should be removed and probably rebuilt.
