I’d reduce the oil change intervals and add Lucas synthetic additive too. Sounds like it’s scored and hopefully better lubricants might postpone the inevitable.The oil pressure isn’t bad considering.
Reduce the oil change interval to what? He's doing them ever 3000-4400miles. And was listening to the oil life reminder in the truck. On my '12 I find the oil life minder is fairly adaptive, did 7000+ miles mostly highway on cruise control before it binged and other times int he winter with a lot of idling it's binging after 2400miles. Or are you thinking reducing it as a result of this "issue" not in general?

When I changed my timing chain and oil pump I did the first two at 100 miles each. After things in the oil filter looked better I even swapped out oil filters in between oil changes.Just me I guess,but the in between filter change is what I do in the rare case vacation time is going to overlap my normal 3k change. It means “minimum” cutting open and inspecting your filter.IMG_2532.jpegIMG_2294.jpegIMG_2295.jpegIMG_2293.jpegIMG_4351.jpeg

I pulled this out of my oil pan and smaller particles after I did the chain ,oil pump with pan off and cleaned. Lots of oil changes after I saw that.View attachment 561591
What in the holy he** is that item?
You could pull the intake manifold,it's pretty easy to remove,then check the screen on the VVT solenoid for metal.It's the solenoid at the front of the engine,the other 4 solenoids in the valley are the MDS solenoids.If the VVT screen is covered in metal fillings,the engine could be toast,not always,but Ma Mopar reconmends a new engine if the screen is full of shiny stuff.
I'd do that first,as the intake is easier to remove then the oil pan on a 4X4
Man!...bringing up that VVT item is a real coincidence on my end...several months ago i got a code crank/cam out of sync...my research led to that VVT item...old 2010 era had plastic screen version that I guess dry rotted more or less,clogged and messed everything up...few u-tube vids and i decided i didnt want to tackle this job and had the dealer do it..couple hours later and I'm like wtf that was quick ,i shoulda did it myself...new screen is apparently a metal upgrade...weird thing is since the fix...my dam idle is now at like 600 when previous was over 700....not happy with that part....
Also for the OP...my hot idle has always been 28-34psi...so im ok with that

Pulling the intake on a hemi is pretty easy,the only thing that might give you static is the hose on the back of the manifold that feeds vacumn to the brake booster,but i usually remove the hose at the booster,as twisting it off the manifolds fitting isn't all that easy,other then that a 5/16 or 8mm socket and 14 mm socket are all you need

For me it was that plug back there......I will say this about this truck...dam near every plug I've ever had to undo has been a real pain...didnt want to possibly break that let alone not being able to see it......I've already done the re-check and torque of all the bolts as you guys have suggested on the intake

I tackled changing my VVT solenoid today. I also had planned to change my intake gaskets and port the intake while I had it all apart also.
I was having an intermittent check engine and the code was P000B.
I did hit a snag with the solenoid while removing it, the old one broke in half or was already broke trying to pull it out. I was nearly ready to call it quit when I used a 3/8 cement wall anchor and simply turned it by finger into the remaining half of the solenoid and then gripped the bolt with a channel lock and tapped them with a hammer. Viola it came right out !
The last picture is what it looked like inside once it was removed. I'm wondering if anyone can give me some info as to what I'm looking at inside that void.
Also after finishing up the job my fuel consumption improved from 20.1L/100km to 15.3L/km
Idle and run oil pressure seemed to improve also as before my idle pressure was very low at 40-50 kpa, my new readings are 140-146 kpa idle and at 1500rpm it's in the 300 range kpa.
The truck also seems to shift and run smoother also now.
