this post made me go look at the LS Swaps .... Im getting ideas

I'm pretty sure the viper engine fits under the hood. A 392 is cool and all but imagine the scream of that v10 coming out of the back.

I mean did it overheat? Normally
head gaskets don’t just give up.

It did not overheat - I changed oil and saw orange buildup that I thought was coolant - resovoir was low but not empty. Stopped driving it and made appointment. They said there was coolant in the oil when it got to the shop.

That sucks!

What'd you do to it? It could be a failure point from the factory, but it kind of sounds like a maintenance/driver error issue. The fact that it lasted 87,000 mi before it blew a head gasket is a little bit weird.

Be curious to see what the outcome of the problem ends up being?

Not sure that I did anything to it. Certainly I drive it, and I tow a 2k lb camper with it in the summer but nothing that I would have expected to cause failure. I have changed the oil and used the specified grade, used 89 gas, even changed the diff fluid at least every year. Like I said in another post, I first noticed coolant (never a puddle) when I was under it changing the oil. CHecked the black reservoir (cause why should I be able to visually inspect the level without taking the cap off, that's just silly) and it was low but not completely gone. It's winter here and the heat still always worked. Never had a temp light or issue. Took it to the dealer after that and they said there was coolant in the oil. Have heard nothing from them in the over 2 weeks since it got there and they told me they would have to investigate. Now waiting. I have the mopar unlimited mile service contract and about 2.5 years left on it. Plan was to drive it until the service contract was done but now not so sure.

Four bangers utilized in large vehicles have been an issue for decades, especially if turbocharged. Yet, the old Jeeps with non turbo, and proper gearing, seemed to fare just fine.

Wait so I only need to make it to 60k miles before I can maybe convince my wife to let me hemi swap it?!

Hemi swap has been in the back of my mind since picking my Jeep up! My Jeep currently lives in Michigan about 15 minutes drive from AMW4x4, so I suppose if I had to replace my 4 banger, it would only make sense to go with a *minor* upgrade. ?

Bummer to hear the OP is having problems. I have about 20k on mine and it runs like a top. I love this engine, but still would have gone with the 3.6L provided I could have gotten an auto without the eTorque at the time I ordered. Even after my 2.0T sits for several months at a time it still fires right up and runs smooth. I'm honestly surprised I don't have battery issues yet, but that's neither here nor there...

Ford makes a 2.7 twin turbo that has 330 horsepower, 400 ft. lbs of torque and will last 200,000 miles easy if you take care of it. How about the Subaru 4 cylinder 2.0 Turbo that will easily last 200,000 plus miles.

So, there is really no reason Jeep can't put a 4-cylinder Turbo engine in the Wrangler that will last. My 2017 Ford 2.7 pulls a trailer every day and I run the heck out of it. And I traded in a Subaru WRX with 240,000 miles that was run hard.

Sounds like it may just be a bad gasket. Rare but not impossible. I have a 2.0T Volkswagen with almost 200k, tuned and still on the original turbo. I realize it's a different application, and I have replaced a few parts, but maintenance is everything.

the 2.0 has a crappy cooling fan profile, coolant hits 220-230 on a regular. Apparently this was done on purpose because the early profile kept the engine much cooler but people complained about fan noise. This is most likely a contributing factor

Apparently the early JLs have an option to get the fan update, but I don’t wanna do it as I’d rather the jet engine go off than it hit 230 in traffic.

It does see 220-230 if I’m WOT from say a heavy acceleration but it goes back down the second i let off the throttle.

I agree, I would rather the better cooling. Been waiting on a PWM fan controller to be designed for the 2.0 at RPMExtreme but they have yet to have a 2.0 enter their shop.

If anyone with a 2.0 is in their area ill pay $150 towards your controller so that i can get mine before these coming summer months.

It's just about due for a new turbo anyway.

I used to worry when towing about getting too hot. I don't think I have ever seen anything north of 220 even when towing in the summer. Fan never ran continuously either.

Is there a way to switch to the original profile? When I lived in Texas, hitting 230-240 was normal, but it always concerned me.

Thatsa great question, Unfortunately i think thats a function of the PCM and so i doubt they would downgrade to an old revision PCM data file
