Engine issues 3.6L

[ShadowsPapa]

Although this may be true:

"And with the millions out there not suffering any mechanical issues at all - it's a safe bet............"

For those like myself with a 2022 JTR and less than 23k miles (always dealer serviced) that has had both intake camshafts replaced already, and had the MIL light come on yet again (when on vacation last week in Moab), the fact that other owners haven't suffered the same issues is cold comfort.

I'll be calling tomorrow to get an appointment at the dealership. Will update with what they find. Based on the "clackity clack", I'm expecting P0300 as the code.

Like someone else here said in better words - the others don't count if it happens to you, they don't matter.

Until the number reaches 0 - someone is going to experience the pain even if 14,999,900 others don't.

I am on my second engine... misfires, tics... cams, rockers, lifters, all replaced...new engine is starting to have more misfire in cylinder 3... here we go again ...less than 18000 miles on it 2022

#3 is an easy spark plug to pull. You don’t even have to pull the intake off. Have a look at it, post a pic of it here! Pull #5 coil and 3 and do an ohm test on both and see if numbers match.

Really? Mine was smooth as heck, just as good as the MOPAR, but with more options.
Are you sure it's not the trailer instead of the controller, or maybe the controller's installation?
Redarc is a top name in brake controllers

Its not the trailer - I routinely tow the same trailer behind my Ford pickup with a factory TBC and it is completely smooth. What the RedArc does is apply brake fairly smoothly initially and then at very low speeds applies too much brake and the trailer lurches to a stop - not matching the brake input from the Jeep. It seems to also not release right away - perhaps taking input from the Jeep's hill assist, but holding the brakes very tightly. I'm pretty sure I installed the Redarc properly, since they let you orient the unit in any direction. I mounted it under my dash near the steering wheel.

Since it's a 2020, IMO, it should be a known issue.
And like you said - it's not that far out, and it's worth at least trying.
This is one reason I suggest that if people feel something is wrong - get it reported, on record, checked out, a work order written up on it. If a loud tick is reported at 59,000 miles and then the cam goes out at 61,000 miles - there's a paper trail, it was reported prior to warranty expiration.
May not always work but there's nothing to lose but the trip and time.

100%

2018 Subaru with 58,### miles, took it in for excessive oil consumption. They did a fresh chance and consumption test which brought me back at 61,### and they replaced the short block under warranty. As with many such things, get it in writing, document, document, document. Paper is your friend because even notionally going to court you'll need the receipts.

There is no way to do it, but I'd love to see the data on every engine that developed the tick and what brand oil and viscosity they were using. This almost seems like it could be a lubrication problem causing wear. Because why in the world would a company continue to install substandard metal parts? That doesn't make sense.

Get one of these to keep oil in galleries https://www.baxterperformanceusa.co...t-ms-201-bk-cartridge-to-spin-on-adapter.html or this one https://www.baxterperformanceusa.com/shop-by-make/pentastar-36l-rj-404-cp-remote-combo-pack.html

Doesn't keep oil in the galleries, only in the filter. Nothing can possibly keep oil in the galleries.
Non-issue with these if you watch what happens while starting these engines.

I’d be a bit worried if I saw this, and in fact I did see this temp right after I picked up my truck from having the second engine put in and the oil filled was extremely over full by 7L. I didn’t check the level but trusted it was good. My immediate trip was 1500 kms and on my way back I saw that temperature and called the dealership. The service manager wasn’t alarmed by that temp and I carried on the highway and got home and did an oil changed to see all that oil in there.

Now, I don’t pull a trailer but can get loaded down with stuff and go on long trips of a 1000-2000 kms and I’ve never seen those temps except what I just mentioned.

We just did a road trip to BC and the photo is typically the range my engine stays in. It can get hotter but nowhere close to 235.

Want to try an experiment? Turn your heat and air completely off and drive around town. Watch your heat reach 222 degrees in traffic. If traffic is moving too much for that then just pull into a parking lot and let the truck idle for a bit. It’ll reach 222 then the fan will kick on. Then take it somewhere with a good length incline (leave air completely off) and watch the temp rise to the 230s. What you see might surprise you.

Around town with ac blowing at all coolant temp won’t get much over 205.

 

[TinMan2020]

Furthermore, when someone says “designed to run hot” they may be referencing the fact that the electric fan doesn’t even kick on until 222 degrees and doesn’t reach max speed until the low 230 degrees. At least that’s what I’ve experienced through paying attention. So if that’s where the engineers set the thresholds then that’s how they designed it. (Running AC changes this fact because running AC forces the fan on no matter the temperature of coolant)

235 scared the hell out of me too. Still not used to it.

I'm at almost 20k miles on my '23 JTM.

First oil change at 1900ish miles and every 4k following that. BUT my break in was drive it like I stole it and no issues other then the passenger side valve cover gasket thats currently leaking.

Sorry I meant to say keeps some oil in the filter NEAR the galleries so it is readily available on start up. The stock filter drains when engine is turned off and thus the oil is not as readily available on startup.

I should also clarify - it's different with engines like the small block Chevy of the past where the filter was below the oil galleries - as well as certain other engines.
It's a matter of system design, filter placement vs. pump and galleries and so on. It's a plumber's nightmare of combinations.

I am going to fit the remote kit as SC pulley in the way.

Hi guys,
The ticking on my engine was at about 4K rpms and I first noticed a faint ticking at 59k miles but it worsen pass the 60k miles and of course after warranty is over.
My fried took it apart and the problem is with the intake cam, roller rocking arms and lifters. One was stock in place. The problem is definitely oil starvation and there is noticeable scoring on the cam sitting on the head. I used Royal Purple but the problem must be beyond the oil brand. If the problem is oil starvation it will happen again within the next 50k miles.
The dealer wanted $5,100 to fix it and my friend did it for $1,100 including parts.
I am pulling the plug and going to the dark side with a GMC Sierra.
Yeah my Jeep was the absolute perfect truck for me, I am still very upset and disappointed. My dad RIP was an army guy that introduced me to the love for the Jeep pickup truck with his 64 Jeep Willys, which I still own, he would have been so happy with the Gladiator and damned it!!!
Thanks,
Javy
