Tick noise p0303

[Camachoe]

Hi all
I have a question on a 2012 1500 hemi, a friend of mine has and his truck has a tick noise. I’m not sure if it’s a lifter tick or injector noise or what it could be. It does have the engine cylinder 3 misfire code (permanent). Truck might need spark plugs soon for sure and an oil change but I wanted to ask some one who knows what they’re talking about before the truck gets taken apart. He took it to a mechanic shop to ask and they told him they might have to replace some internals. So we wanted to ask before we took it to the shop!
Thank you all for any input

Take off the Valve cover and check.

Move your coil around to see if code follows

Check Manifold bolt.

Definitely not injector noise.
You could first swap #3 plug with any other and see if code follows, then do the same for injector and coil, swap one at a time.
Or as Dilligaf suggests, and I would recommend with that much noise, just remove the drivers side valve cover, it is kind of a pain but doable. You or your buddy crank while the other watches rocker arm movement. I suspect #3 won't be moving much.
For reference, here's my lifter failure noise, also #3 interestingly:
2014 lifter failure
and here's the culprit:

Hopefully you get lucky and the noise is something else, but your friend should brace himself for the worst.
The next decision is whether to trade the truck in, sell it, repair it himself, have it done, or swap in a used or remanufactured motor. Good luck.

That's the classic noise of a lifter gone down. Stick a fork in her, she's done.

Smart move. If you are tearing it down might as well replace as many parts as you can while you are in there. Save having to do it again later.
