3.6 or 2.0

[croppz]

No i'm not going to waste my time on this. I don't care what you think.

Expected answer from you lmao

Both are fine, just different. The 3.6 is smooth and predictable. The 2.0 is peppier and not as smooth or refined. Both have problems. The 2.0 has more that are pretty much guaranteed, but pesky more than catastrophic. The 3.6 has fewer pesky/guaranteed and fewer overall, but if you win the ticking lottery, oh fucking boy. Same Jeep, different motor...

This is the truth. It's always been the truth, and it gets stated 100 different ways in every single one of these threads. This will continue forever, apparently.

At least alphawolf came with the issues he sees, most werent special to the 2.0 but he at least came with some.

I'm buying a vehicle, not an engine. If I can buy a factory drivetrain combination at relatively the same price that out performs the other in any combo offered, the winner is the winner. We all have different preferences and probably goals.

I think I've beat a dead horse with my opinion over the 2 choices on this forum. Both are fine, just different. The 3.6 is smooth and predictable. The 2.0 is peppier and not as smooth or refined. Both have problems. The 2.0 has more that are pretty much guaranteed, but pesky more than catastrophic. The 3.6 has fewer pesky/guaranteed and fewer overall, but if you win the ticking lottery, oh fucking boy. Same Jeep, different motor, I'm going with price and availability every time. Given an exactly equal choice I honestly don't know.

I think the only 2.0 ones that are almost guaranteed are the coolant T and the coolant reservoir bottle. At some point that plastic will get brittle. (Though, again, I have seen the same/similar failures with the 3.6 and coolant bottles/connectors on the forums, so I don't think it's engine specific, just more a "Modern plastic shit breaks" situation. More prevalent on the 2.0 due to heat output, maybe, but not unique to it.)

I view the tensioner issue in the 2.0 like the cam issue in the 3.6 - lotto dictates whether you win or not. Thankfully it's one of those issues that warns you for a bit before it becomes a problem.

And, TBH, I think the cam and head/head gasket issues aren't HUGELY widespread. Just more common than one would hope.

Timing chain tensioners are also not an uncommon failure in any other chain engine. They get replaced along with guides when you do standard preventative maintenance on them.

Unlike Cam Shafts ......

Apparently we need to make sure the 3.6 has different gears than the 2.0 because it needs the help.

i feel like the 3.6 JLU with 37s and 4.56 does great off road and at speed. Where it annoys is a very steep windy road where you’re limited to a max of about 40mph and it doesn’t feel optimal until you force it to down shift, then it feels like it wants to wind out too long before it will upshift. Repeatedly. Maybe better gearing is needed on a piggish JLU with too much offroad what if stuff?

 

[ASSFROW]

But it's not valid for comparing the engines if they're not operating under the same conditions

What's awesome is we don't have too.

4.88s honestly would probably help. Even with the old NAG1 in my JK, the 3.6 really loved 4.88s and 37s.

And I do trust what he has to say for sure. But also not the only guy that sees this stuff every day.

The 2.0Ts issues are obvious and easily/well documented. I still will take them over eating cams and bad heads/head gaskets from nothing other than stellantis’ pure laziness to actually fix it over the last decade or so. But also, literally every engine offered has issues. Not just from Jeep.

IF it weren't for the failures that we are seeing on the 3.6, I don't think that its power is that far from ideal for the Wrangler. The non PUG in the JK with the manual felt pretty good, you just had to keep it wrapped up to the higher RPM range, but it surprised me at how quick it was. And the JL with 4.10 gears in Rubicon trim would quickly light up tires if you aren't careful, and even after putting on larger heavier tires and wheels, I could pretty easily break them free from a stop.

yea 300hp/tq is plenty in a Wrangler for doing Wrangler things. Its not a race car, its not meant to go 100mph its not meant to get 50mpg. Its meant to meander around town and idle over rocks.

The PUG needs an outside solution for tri-metal head gasket, arp studs, new non VLL cams, and oil cooler design change, and it will be solid.....

SO tell me more about the 2.0L

It sounds like a tractor grinding up ball bearings on startup and scares old people, but it's aight

Great low end torque, solid MPG, has plastic coolant fittings/tank next to a hot turbo that’s easily fixed with aluminum parts. Wastegate arm rattles on decel but not a problem. Doesn’t eat cam shafts

Sounds like a tractor on cold start which scares soccer moms that don’t let cold start sequence finish before going to Starbucks. Warmed up it sounds fine
