I agree, and if the rumors I've heard are true, the valve seat coming lose in the head, that would severely damage the piston, cylinder and even more if it were at freeway speeds. The seat would move out of the head, the valve wouldn't close completely, and the piston would hit the open valve....boom!

You guys are right IMO. If the piston is "kissing" the valve/valves as was mentioned a few times, it is not good. While there are no catastrophic failures that I've read or heard about I would bet it can and will happen sooner or later. I for one would not drive it until it was fixed. Then it would be a third vehicle in a family of two, so my situation is different than many of the people posting here.

Wouldn't it be nice if Chrysler would just level with us so we wouldn't have to GUESS at what might or might not happen. You would think as customers they would let us in on the secret. After all, we spent $30k+ to join the club. Hopefully they troll these threads looking for customer sentiment.

Just by the fact that our resident Chrysler employees are quiet in all of this indicates to me, Chrysler is going to share as little as possible, and probably told their employees to keep quiet. We gets bits and pieces of info, put it together the best we can and speculate on causes, cures, or what they might, or might not do. Typical of the auto industry, and I wouldn't expect anything different in this case. I still maintain when the resident insiders say it's fixed, then it's fixed for sure. The jury IMO is still out on this one. JMO

Sad but undeniably true. Time to work on my patience. I guess it's a just a matter of time. I have two Pentastars to wonder about. Thankfully they both are still running quietly. 7k on the JKU Sahara and 11k on the T&C.

Demarpaint,

Do you have or have you had the ticking problem?

You might not have a problem, and it sucks to have to wonder about it though. Some people don't care and will deal with it if/when it happens, unfortunately my personality doesn't work that way. What I mean to say is now that I know there is a problem, I parked myself on the sidelines and will continue to wait until I'm sure its fixed. Heck that might put me into the 2014 model year, honestly I don't care, nor do I mind. I have my heart set on a Wrangler, and it will be a tough sell for me to buy something else.

Thanks. Adventure? Hardly. When I'm ready I'll buy, it's that simple.

Good luck to you too, you might be OK. I would look into seeing if removing the insulation helps to prevent the problem. Some people are saying it retains too much heat and could be contributing to the problem. You might want to look into it. Maybe removing it in the spring and reinstalling it in the late fall might be helpful.

Unfortunatly demarpaint, Its all guess work until the execs say so. I like the rest of us, am sitting and waiting. But it hasnt stopped me from driving my new jeep. But I did take the top cover off,

To me I like the idea of the engine releasing any thermal heat buildup. Weather or not it is actually doing any good will definatly start another heated debate. I am not looking to start a debate, its just something I did.

In the meantime, I am driving, and enjoying. Hopefully this will be over soon enough..

Yep when the execs lift the gag order all the guess work will be over.

Excess heat can't be good, and that engine cover is there to muffle sound, but in the end its also holding a lot of heat. In the winter that would be a plus, in the hot summer I'm not sure its all that good. Yea something for more debate, but it might help.

Enjoy your Wrangler! I hope this ends soon too, and the Pentastar goes down in history as one of the best engines from Chrysler, that had a little hiccup in its infancy.

I was under the impression that the plastic engine cover was there to shield the hood and that the paint would blister without it. I would remove my cover in a heartbeat, especially on the trail, if it wasn’t necessary. Is anyone driving around without the cover?

I know of a few people doing it, and a few more considering doing it. I can't comment about the paint issue, but if it is throwing enough heat to blister and peel paint then it gets very hot under there and that could actually be a possible cause for the head failure. My understanding is it was there to deaden sound, but you do bring up an interesting point. There is no insulation of any kind on the engine or the hood in my 08 Liberty [granted its a different engine], but I have no problems with paint failure on the hood.

IMO leave the jeep the way it was designed and built. Go enjoy it! If something should happen, deal with it at that time. If you start removing covers and who knows what else, you never know with auto makers, it might come down as your fault as you altered the engine! Probably not, but just saying!!

Okay last time I checked engines have been under hoods 4 decades with no issues of paint bubbling peeling or coming off with out any engine cover lol. Engine covers are for aesthetic reasons only.

Anything is possible that's for sure. Which is why owners of the 2012 should use 5W30 oil and owners of the 2013 better use 5W20 oil. The cover is easy though, the people I spoke with said if they have a problem they'd put the cover back on before visiting the dealer. Not exactly honest but then again who am I to judge? If it averts a problem then it was a good thing to do. I'm just passing along info I found in my travels.

I forgot to put my cover back on after I did my first oil change. As another poster said, engines went years without them. I say its for looks and maybe help quiet down the engine compartment. Don't remember if mine had the insulation on the underneath of the hood or not though.

Duneyeti, I am running without the cover on. I have no insulation under the hood of my Tj either,That paint is just fine.

I may put it back on in the the winter. But right now being so hot. I personally do not see the need for it.

Thanks, my temp gage has always been rock steady but it can't hurt to make it's work a little easier. I want to put a skid plate on but now I'm worried about what Chrysler is going to blame on us owners next. Bad gas, driving habbits, skid plates?

Dropped off my JKU 2012 at the dealer today to have the head replaced. Service Rep said I might get it back tomorrow. I hope I get it back soon because the compass they gave me to drive is.... well lets just say it's not a real Jeep :{

I really have no intention of sitting the 2013's out, but I do have to admit...it is a bit spooky. I don't want to spend $32K on a known problem with very little information coming from Chrysler.

Yea it is sure is spooky. I'd give the 2013's a little time, to get some more on the road and log some miles. You'll know long before the 2013 model year is over, then decide. If you're like many others and don't care about the issue, or feel like taking a shot at it since you have a warranty, etc. then go for it. In the end it all boils down to whatever makes YOU happy!

It's a shame they posted the fix, at/near the end of the 2012 model year, just about the time 2013's went into production. That's the scary part about the 2013's.

Well, ten days later and three CEL lights on and three trips to the dealer, and just like they said, they ordered the head...it should be to them in the morning, and they are giving me a free loaner vehicle. They have actually been very good about this, and they will now be my service center of choice with my Jeep. The place where I bought my Wrangler had a terrible service dept.
I think it helped immensely that I knew about this issue and let them know I did. I was respectful to them, because they were right upfront and told me that Chrysler has a process of steps for them to follow before they can order the head and get a loaner paid for and approved. It's a couple re-flashes with updates, so long as the codes clear and stay off for their road tests. Then the third trip back in with the same code and they call Chrysler, order the head and clear a loaner.
BTW. They said they ordered two heads today, one for me and one for a Caravan. They also claimed that it should be ready tomorrow afternoon or Wednesday. They then stated that they have only been doing driver's side heads, so they don't even believe there is a redesigned head for the passenger side. Hmmmm. Either way, it's all free! Life is Good.........so long as they do a good job here. Lol. The manager said he only has one guy that does the head jobs here, so I like that. I'll keep ya posted in this thread

14,484. CEL first appeared at 14k, but I started noticing ticking at around 4k-6k miles. Had it documented.

@Braveheart - so between 4 and 14k aside from the ticking - were there any other problems?

Thanks. Good to know what I might encounter. I'm at 6,868 miles. No ticking yet.
