Drove around yesterday the tick is gone and seems to have a little more power than it used to and my mpg have increased. I would advise people to forward a link to this thread to their service manager and mabe inlcude some youtube videos of their engine sound and some vidoes of a jeep that has a head replaced and maybe ask them to start up a 2012 on the lot and show them the tick is not normal
Re: the bolded, I was told by the dealership that Chrysler won't approve (pay for) the warranty work if no code and/or CEL has been thrown. So if I wanted them to dig in there to do stuff, it would be on my dime.

This is true for Ford as well, my friend had a '04 or '05 (cant remember) F150 and something was going wrong with his cam and it was causing it to tick, but it wouldnt cover it because no check engine light was thrown

Not sure why they told you that. If something is not right its not right wheater a code pops up or not. I would aslo try another dealer. my dealer tried to tell me it was normal so I just picked it up and took it back in 3 days later. plus here in NC lemmon law states they have 4 tries to fix the problem that might have helped i dunno though I also emailed the service manager a copy of the stuff I mentioned in my previous post plus a copy of someone elses service tick who had their head replaced so it was clearly not normal for the engine to tick

Has anyone called an independent shop to get a price on a leakdown test? I would think that would be a good way to start documenting any potential issue.

Lots of people think its under warranty just give me a new one for whatever problem they have. If the dealer cant prove a failure they and or the tech will have to pay the bill.i see it happen at work all the time.no i don't work for jeep,but close

But this is not the first year of that engine. First year that it in a wrangler, yes. But the engine has been out for a while.

2012 penstar motor noise, we have same problem, we took ours in two weeks ago to local dealer, they advised that the lifters were loose. And they need to replace both heads and lifters,timing chain.. We were told it would be three days, it was two weeks,picked up friday night drove home sounds ok, started next morning (70 degree weather) it made terrible noise it did not make till this work was done, only last few seconds till the oil gets up into heads. But still not right.. this sounds like long road of motor trouble? i wonder if jeep has corrected the problem in 2013.

Well at least in your case they did the right job and swapped both heads. I would not want one head swapped on an engine that had lets say 10,000 miles or more on it. Anytime I swapped heads I did them in pairs, that's how I was taught and IMO it is the right way to do the job.

As far as them fixing it for 2013, it all depends on how many motors with defective heads are in inventory. There are now April 2012 build dates with the problem.

I have a little to add, and it's not fun...

January 12 build Wrangler Sport. Has 724 miles. Been to the dealer 4 times initially for loud clanking tick...was told it was normal. So loud that the girl at Taco Bell couldn't hear my order; had to shut off the engine. Finally threw a code, cylinder misfire. Dealer replaced cam phaser and lifters on left side. Came back with massive oil leak due to dealer forgetting to tighten something...never did find out what. Went back to the dealer, fixed oil leak. Got Jeep back...ticking louder than previously, horrible rough idle. Brought it back, Dealer says noise and rough idle are "normal for a Jeep" again. Notified dealer of head replacement issues, threatened buy-back. Contacted Chrysler, started a case file. Dealer called ME, said would replace the head. Left head replaced, got Jeep back. Driver's side of engine quiet. Now, immediately, passenger head side loud ticking. Again, told it was normal, and to drive it to let it "break in." Had it for a day. CEL light again, this time towed back to dealer. Called Chrysler. Both heads then replaced at same time by dealer, don't know why both were since driver's side at previous replacement was finally quiet. Got Jeep back, both sides seemed quiet. Drove it about 200 miles in one day, sudden loss of engine power with check engine light. Towed to dealer...cylinder #2 misfire CEL. Not only that, valve bent with interference, top of piston cracked, metal in oil. Chrysler wants to replace left side head again but nothing else. I've been nice through the ordeal, but I will not accept any more engine repairs. It's either a new complete engine with verified properly made parts or a buy-back. I haven't heard from Chrysler since Thursday. Come Monday the nice hat is off and we switch into possible litigation mode. 724 miles.

Exclamation

Well, as you folks know, at 1300-mi my engine died twice (towed in both times) and a died a 3rd time during dealer test-drive after repair two! (11000 on her now)

They claimed I was burning out coil-packs due to a short

Was goin to sell it due to a complete lack of confidence in the vehicle! But heck, I have the Life Time Warranty, so Chrysler has to pay for the repair/labor and furnish me a Loaner On the other-hand I may go 300K miles with no further problems

I am always getting compliments on my Jeep, so guess I am going to keep her

Seems like Chrysler is terrible at this, and are trying to get away with the least possible expense but not fixing the problem for good. I'd explore all my legal options if I go through this. I detest being taken advantage of or treated unfairly. What does it take to initiate a recall- accidents? fires? Do affected customers need to start writing to the NHTSA and their Senator? I think it's time to start doing that. Enough letters and they will get involved. I would, and I'd definitely look into invoking the Lemon Law if applicable.

Share our problems with "Fox News", one time, and Chrysler will act

Although I had some real electrical problems with my unit, being towed in twice and in the shop around 18-days total, I have not had the head-failure as yet Therefore, I can not make the call to Fox News, but if the call is made, I will gladly share my story with Fox, as I am sure others here will also!!!

Looking at the suposed repair they made to my Jeep, I now doubt the story I was given as to the cause of my engine failures The 3rd engine-failure happened as the Dealer was test-driving it after repair #2

I believe you can pursue with the "Lemon Law" if you encounter the same parts failure three times within the course of a year...

Update for y'all:
1. Noticed Ticking on driver side at about 5000 miles. Dealer changed oil, no effect. 2. 9700 miles took to dealer with ticking complaint. "Could not duplicate" (I was told this is "Normal injector noise")
3. At 10500 miles the check engine light comes on. Dealer notes p304 failure in exhaust valve on Cyl#4 and replaced head.

Apparently dealer does not take this seriously until you blow a code. Also, I did not note any loss of power or gas mileage. I was still getting 20.5 average mixed driving/ half freeway 70-75 mph.

THAT is an immensely important question! I bailed out and sold my less than three month old Jeep out of fear that the replacement heads would be no better than the originals.

I hope all of you guys who are following this thread have also posted in the thread I started that has a poll about the head problem. It helps us to see how prevalent the problem is when people participate in the poll.

http://www.wranglerforum.com/f33/pol...em-158389.html

Yes, I bailed out and sold my Jeep but I still care about how this turns out for the rest of you. I hope for your sakes that I over-reacted.

There has been one or two cases on this thread I think, but most replacements do not have the miles on them yet for the typical failures to show up yet. So it is really too early to say for sure. Very quiet from Chrysler on whether the new heads are a "fixed" head or just hoping to get a good one next time.

very happy to read that, JayDee. admitting a problem is the first step, as they say. however, if they needed to fix something and apply it to ALL engines, then i would consider all current heads defective in some way. it's probably a matter of mileage until the tick surfaces. Unless only one head casting machine was affected out of the entire production line.

if it's true that a fix is on its way into all the new engines, it's clear that people who have had a head replaced probably got a defected one again. i decided to hold off on the dealer cracking my head open and i'm glad i did. if this is a quality source, this is a great news for the pentastar. it's a fantastic engine and a little teething problems are expected.

i/m sure they had these new heads in production a while back. they were using them to supply dealers doing repairs but continued to sell motors with defective heads. I'm sure the replaced heads are all good to go. they must have a sgood supply of them now and that is why they are finally talking about the issue....they would still be silent if they were just beginning to fix these.

good to know they are admitting the problem.

Tomster: you bailed a week too early brother!!!
