What do you mean YOU people? Lol just kidding around. Dec 11 build almost 47k and still driving the piss out of it. No tick other than normal
You're the 2nd person I've heard whose got 12/2011 build driving the piss out of it with no issue. There's a guy here with a RIPP supercharged also built that same time, and his motor is also holding up just fine.

I've got a 12/2011 build as well...for a while I thought I had the tick, but after 8k miles the motor has gotten quieter and now I'm starting to think it's just the injectors. Actually getting quieter & smoother the harder I drive it. And MPGs are finally starting to increase also...

Could it be that the Pentastars built in 2011 were good???

The head replacement paperwork said they purged the coolant during testing and refilled and purged the air however apparently there was still air pockets that used up all remaining coolant...odd. I went back to work and let my coworker know the results. He went out to his jk which got a head replacement about 3 weeks ago and found his had almost no coolant either...now mind you we each went to a different dealer for warranty repair work on the heads...my mind is boggled, good thing we caught this. Not sure if its a common issue or we're just 2 unlucky fools haha. However I was pleased how fast the dealer was today with testing and fixing the issue, all for free.

Sounds like the tech that did the job didn't properly bleed the cooling system, then run the engine until the thermostat opened with the heat running, let it cool and check the A/F level. Good thing you checked it or you could have seized the engine.

I would keep an eye on the coolant even though they tested it. You never know, you could have a leaking head gasket.

Yea I'm gonna keep a close eye on it along with my co worker. So ironic that we both had head replacements at two different dealers and both of us had no coolant barely. Hopefully it's just us two and no one else. I'm sure the system either wasn't bleed properly if at all or it was bleed and they just never topped it off afterwards. Paperwork says it was done but who knows.

Well, i'm really confused now. Mine stopped ticking, it seems to come and go and i don't know why. The dealer says it is fine and just drive it. Sometimes it ticks at startup and other times it is totally quiet. This is crazy!

Lifter noise. Completely different issue then the head issue.

How do you check? It says nothing on my paperwork about what kind mine was replaced with.

Good idea to keep an eye on it hopefully it was a simple mistake, and nothing more.

The part number should be listed in your paperwork.

AC head is RL141353AC

Hello Rubicon Jim,

I see you live in New York, this is just a thought, maybe they're saving the water for bagel and pizza dough.

Mine just got dropped off today. After looking it over and checking everything out, dealership told me its normal for a jeep to tick, some tick more than others, some are more subtle, some do it on start up and then stop, some tick the whole drive..mine ticks the whole drive., go figure! It's annoying, but I guess it's somewhat of a jeep thing?

42k on my 2012. Dealer did a leakdown test on mine 15k ago. Tested within specs but have the tick and 1-2 mpg decrease. Within a week after getting it back noticed the coolant was quite low. I filled it back up and fine since. I think some mechanics are being sloppy with the refills.

More than likely that's the case. I do 99% of my own work. In the rare event I have work done I check to make sure things like the oil and coolant are properly filled if the repair required draining them.

I've had transmissions serviced a few times, and I'd say out of 5 services the transmission wasn't properly filled 4 of those times. The good news is the coolant is easy enough to check.

If it's any consolation, the Service Manager at my local dealership says he is not aware of any failures so far on the AC heads. They are a Toyota/Chrysler dealership and do not sell many Wranglers. He says the Grand Caravans definitely have had the head problem and they have had to replace lots of those heads in their shop, but no AC heads have failed so far.

Another casualty here. My 2012 JKUR (bought it in Dec 2011) with 21,300 miles went in with a check engine light, and the dealer confirmed it's the head. It's not a big deal because it's under warranty. I'm just excited to get it over with. I started taking it in for the ticking at around 8K miles, and they told me to bring it in after it had a check engine light.

I ve posted numerous times in this thread, and had a similar thing for me at the dealer yesterday. (BTW, I have a 12 with a may build date with 15,000 miles and no issues.) I asked the guy "..... Are you guys replacing a lot heads"? " OH yes, a lot on the 3.6" He says. " Will you do a leak down test with out the code being thrown?" He says, "No just wait for the code, I can tell you how to make it throw the code,.... drive the hell out of it when it's cold "
I said I don't want to cause a problem he said" ...... well if you want it to throw a code then drive it hard when it's cold". He repeated.
Interesting, I thought. He told me the same thing last time, it's like he tells everybody that, cause he surely didn't remember me.

I have a private service manager, this is the tool they use to refill the radiator after a head change.

Good to hear...any idea if the 2011 builds came from a different facility?

Great idea...expedite wear & tear on ALL moving/lubricated drivetrain components in hopes of being able to get a new head.

May as well just open the motor up and physically damage the #2 exhaust valve.

Worried

Hey guys,

I've looked through a handful of the first and last pages on this thread and have seen the YouTube videos. I'm worried about the 2014 Sahara I just ordered as it will be my first new Jeep. Have the issues been worked out yet? Are recent '13 builds or fresh '14's having this ticking problem still?

Thanks

Being on the thread for over a year, read about one possible early build 2013. 2013! Overall is fine as well as your 2014! Enjoy it

Well, hoped to never post in this thread but....13,765 miles in my CEL came on today with a code for misfire of Cylinder #2 on my 2012 JKUR. I had been noticing that my already not so great gas mileage had been getting worse over the past few weeks dropping from 15-15.5 mpg around town down to 13-14 mpg despite driving the same places and the same way. I have also noticed the ticking noise for some time now, but as many have said this could be normal, never bothered with taking it in as I figured my dealership would just say it was "fine." Figured why waste my time.

Now the interesting thing though. After driving some more later on this evening and turning the Jeep on and off a few times, the CEL light went off and is not lite up anymore. Guess I will wait to see if it comes back on or not before I schedule to take it in.

If it came on, the code should be stored in the computer even if the light has gone out again.

Yes the code is stored for a while until the vehicle goes through a few start stop cycles. If no problems occur it is deleted from memory, if the problem occurs again the CEL will light up again.
