The thing is I was I've already had one small turbocharged Jeep. My Renegade had the 1.4 with the turbo. It's not like I'm against the idea entirely I just don't want it one in my Wrangler.

The 2.0 is quite a bit different than that 1.4 though. I've had 3 Pentastar variants, still currently own one of them (and intend to keep it long term), and so I'm not like anti-3.6. It's an OK enough engine. But the 2.0 really is a standout pairing with a Jeep.

The whole uncomplicated angle always makes me laugh with the 3.6. There's is NOTHING that is uncomplicated with this V6. I say this as someone who currently owns one and used to own two other versions of it (OG 3.6 and a 3.2), and doesn't even dislike it. This engine is every bit as complicated and full of harebrained modern construction techniques as any modern turbo.

Your oil cooler is water cooled, your EGR is water cooled, your intake plenum is plastic, you have VVL and VVT, your multi-pressure oil pump can operate as low as 6 PSI and be in spec, you have to remove the intake plenum to do a simple spark plug change, and on and on. The 3.6 in a JL is pretty damn complicated.

So what you're saying is either way you're getting a turd. Just because one turd swirls faster than the other one doesn't actually mean it's not a turd. Nice.

I don't think either is a turd. I think people are scared modernity unnecessarily and seem to think that the 3.6 isn't modern. Both are good engines, but the 2.0 is gooder and has fewer design flaws (oiling system in the 3.6 has a couple well known issues that you have to keep an eye out for), particularly in the context of a JL or JLU.

I mean, okay. Whatever.

If you want to argue with guys who haven’t tried these engines who have opinions on them, knock yourself out. Me personally, I had a V6 for three years, then a 2.0T for three years, and decided I didn’t like the 2.0T so I went back to the 3.6. I just don’t like small displacement turbo 4s in this application. That’s my opinion. Buy what you want to buy. I’ll do the same.

That is an opinion. One not shared by lots of Jeep owners.

I dunno man, whatevering it when it's legit facts about the engine construction seems a bit silly. You like what you like, that's fine, but let's just not pretend that the 3.6 is something it isn't.

The gooder, yes, and being a better fit for the JL/JLU, yes, but fewer design flaws does seem to be an accurate assessment of fact. The 3.6 with its cam & lifter issues, new VVL and VVT software issues, and head issues (some attribute to head gaskets themselves, but MLS head gaskets don't fail unless there's a head trueness or head attachment issue) has more systemic problems. The 2.0 has fewer overall systemic issues (occasional cooling issues, typically brought on by poor installation of the engine, similar to the 3.6's head issues).

My experience has been different from yours. I've seen far more complete engine failures from the 2.0l than the 3.6l. From my experience, the 3.6l's issues are less often fatal than the 2.0l's issues.

So no, it's not fact, it's just your evaluation vs mine (or anyone else vs anyone else).

Total number of engine failures reported on a forum is very different than what I stated. I stated number of systemic issues inherent to the 3.6 are higher. Which is an accurate assessment. And again, I paid my own hard earned money for a 3.6. I don't dislike it, but facts be facts.

The Pentastar's oil cooler is itself water-cooled?

(I've a 2.0T in my JLU, and thus am not as well-versed on the esoterica of the V6 as you other gents, thus my question.)

Yeah, the oft-maligned plastic oil filter/oil cooler housing has a coolant line that does the oil cooling. If you replace one you get to deal with not just oil leaks, but coolant leaks. The oil and coolant passages are separated by rubber seals and the housing has had a bunch of different revisions because they're prone to failing around those seals.

That was just one example...i felt it was far more important than "systemic issues" which could be something as simple as burning slightly more oil than normal, and also a lot easier to see. But I still disagree, the 2.0l is more problematic than the 3.6l. Your claim is not fact.

Lots of people buy McDonalds too, if we were to go by the majority for everything we would never have progress.

Ah. Understood. I was picturing something different.

As someone who drove Pentastars at altitude every day for six years, and then made the switch, I can tell you those people are full of shit.

Man, don't let people like @TheRaven hear you say that! The full of shit part especially, since shit would screw up the accuracy of their "calibrated butt sensor"!
