Nah, we all know the 2.0 would beat the V6 if push came to shove to have only one engine in the JL. The JT gets murkier because of towing and Jeep's less-than-ideal cooling stack, but if they had to cut the JL/JLU fleet over to a single engine, it'd be the 2.0.

And, since it would be the V6 that goes, it wouldn't be able to be a coolant soaked hole since the V6's coolant issues are generally internal when the head gasket goes. We would have a cam shaped hole, a head gasket shaped hole, or OFA shaped hole.
We really have to get a wheeling trip together. 🍻 🎃

Try this: hold foot on gas + brake and press start button. Engine will turn over but not start, and as long as you keep both pedals pushed down, it'll run the starter for 10 seconds. This will prime oil pressure, and if it's the tensioner, may pump it up so it won't rattle or will reduce the rattle when you start it. If it's not the tensioner you'll still have the rattle when you start it normally.
I’ll try that although I only hear the rattle maybe 50% of the time so I’m hoping it’s just the wastegate actuator

Okay, I couldn't read it all.

Have the 3.6L with 6spd manual and love the steady torque ... though I do have the 4.88's to help spin the 35's so 🤷‍♂️

I've driven JLU's with 3.6 and 2.0 and I noticed the auto strongly prefers the 2.0. SO... I've been looking for a 2.0L even though I have a deep mistrust of turbo'ed engines after my Subaru debacle.

Either way, I'd rather have the V8. 🎃

What is interesting is, that the Gladiators are only offered with the 3.6 engine, and not the 2.0. There must be a reason for this. I wonder if the concern was a lack of longevity in that application, or possible overheating while towing, or both. :facepalm:

It probably has everything to do with thermal management based around towing. And the 3.6 is probably the better choice for those that tow regularly anyway which would be the only reason to get a JT.

But personally if I’m towing regularly, I’m not buying a JT or a jeep at all

Uhh, Gen 3 Hemi debuted 2003 so 23 year old , revised with VVT and upgrade internals in 09. The only major upgrades, but has evolved. Perhaps they should re-continue the abandoned years ago Gen 4 development ?
Who, in their right mind would continue development on an iron block, light duty vehicle engine in 2026? Hemi's are ancient boat anchors. GM and Ford have done 3 generations+ of aluminum block V8s since anyone last changed the Hemi boat anchors.

Uhh- iirc it was an ~ 5L DOHC TT.
I don’t recall aluminum, but most likely. Mopar Insiders was on it, but my search skills suck, only finding a clip referring it on another article talking about it.

I'm game. For the next year or two gonna have to be east of the Mississippi though probably. After that the little one should be old enough to travel.

Bro. Stellantis/FCA hasn't learned in 20 years how to keep their V engines (Pentastar and Hemi) from eating their valvetrain with single cams per bank, now you want to double the number of cams???!!!

Why can't you just accept that they only know how to make inline engines with the European Fiat/Alfa/Maserati/PSA technology. All the engineers who knew how to make engines in the American side of Stellantis are dead or retired.
