Ticking sound coming from driver side head of engine

Just noticed last Friday a loud ticking coming from the driver side head and into the wheel well. Should I be concerned? Sounds like loud injector. Neighbor said the 3.6 is notorious for bearing in the rocker going bad.

Can you record it?
My 18 (1st gen pentastar) is clicking also but is not loud enough to be distinctive on video.
IMO bearing will need some mileage to go bad unless its starving oil badly.

Under warranty right? Take it back to the dealer if you have a decent one and are concerned that much. I’d suck as much out of FCA dealers and mechanics as I can until the warranty expires.

Sound very similar to mine, I don't like how it sounds either but without CEL or any other additional symptoms I decided to ignore it.
Weird is that we have two different engines mine is 1 gen yours is upgraded but they click-clack like twins

Yep it’s gotten better so until it throws a code I’m just gonna enjoy it and ride the piss out of it. Life’s too short to worry about this kind of stuff. Lol! Keep me posted if things change with yours.

I was shocked at how loud a 2019 JLU was ticking at a local gas station while the owner had it running while filling the tires with air. It was loud, not normal. I'm positive it wasn't the injectors ticking. I'd be running a 30 grade oil in the PUG upgrade, in-spite of the writing on the oil fill cap.

Shouldn't tick at all. Needs to be looked at.

Bingo. Ticking for a second or two when first fired up after sitting for a long period of time is considered normal. Ticking after the engine is running and warmed up should be checked out. Having said that be prepared for a run around if you have ticking and no CEL. Some dealers can be real difficult and blow you off w/o a CEL.

It is also beneficial to know the difference between injector tick and a tick coming from the valve train.
