True, but it might be partially to blame for the Pentastar tick. No one else came up with a better explanation, and several people have theories heat could be a contributing factor. Sooner or later the reason will become known, for now just an educated guess that's all.

Any ideas what might be causing the tick, other than heat and a poorly designed head? Sure sounds better than the lame excuses offered by Mr. Lee. When an answer is unavailable all there is are guesses, educated and uneducated.

considering this is the internet and all guesses are better then nothing I am going to guess it is a conspiracy by Jeep to talk to alien life form. Yes when just the right combination of jeeps are running at just the right rpm level in just the right places it will be kind of like close encounters of the 3rd kind. Think about it. an untapped market selling Jeeps to outerspace creatures hmmm?

If I have time this weekend I will pull mine off and maybe snap a few pics.
Might be easier to hear the ticking if it happens.

if you want pics of it off, i can take them. i don't think a piece of foam is going to affect the heat, which is why i'm getting it put back on. there must be a reason why chrylser let the dealer order a new part and why 2013s have the foam still. if they thought it was causing problems, the very first thing they'd do is remove all the foam.

Maybe not, after all Chrysler said heat isn't the issue so they wouldn't worry about removing it.

But the foam has to trap some heat. With the foam insulated cover, my engine takes forever to cool down.

i have a sport, so it has no hood insulation. if my hands get cold at night, i can just go in the garage and warm them by the jeep's grill.

I put an AFE exhaust on my 0'12 sport and cold air intake when new. 4K miles and no issues yet. I wonder if free flowing exhaust may run cooler and help if heat is the issue. Fingers crossed.

It could be as simple as localized heat with the left side of the motor. With the compact engine bay the Wrangler has, the steering column on the left side, maybe not enough air flow.

There isn't anything wrong with the right side, just the left side. There's different castings also left vs. right, so maybe that's been corrected. Still, the valve guides being "unserviceable" is a red flag, as is the spark plug tubes being susceptible to stripping. And those are some long spark plug tubes from what I've seen from the schematics. The motor isn't a backyard mechanic's dream motor.

Shopping for a new one what pro date would you look for to avoid this problem? Or is this still an issue with the 13's? I tought I read somewhere that they redesigned the head or am I wrong.

They have redesigned the head twice and from what I''ve heard the problem persists on the 2013's.

Hey guys, approaching 3,000 miles on my 2012 JKUR.... Sounds like the " Tick " is slowly creeping on.. I noticed it last night. I waited for this new motor for two years... Special ordered in September of 2011 and got her in October... Just a year old! I understand they have a fix! But I'm no where near close to being OK with major engine work done on a $40,000 vehicle with 3000 miles on it! I'm always on the forums getting info and reading up on this topic...The dealer I bought from is an hour and a half away.... Don't feel like making that trip 50 times, and am not looking forward to dealing with another dealer near my home! ( I was working up north at the time I bought her) curious to how many of you guys considered or are considering trading your jeep in because of this? I keep vehicles a long time... And although this isn't my DD... It was gonna be my long time jeep.. How have everyone's experiences been up to this point with the dealers?

I dont understand. If the redesign doesnt work what is the fix for the ones that already have the tick with the old head?

Excellent point! I am likely only a few days away from a 2013 purchase and the potential for incurring this problem has me more than a bit nervous. Fingers crossed!

Exactly my concern.... Also what are the after effects long term after the work is done? I don't have time to be going back and forth to my dealer... Reflashing... Then again then again.. And then leaving the jeep for a week only to find other parts missing... ( foam insulator) I need to find a dealer I can go to once!! Make the appointment and get it done when the parts are in. I still hate the fact that my brand new Jeep needs to be torn into! Justs makes me uneasy...

Sure hope not! Maybe that AC head is going to be the answer.

What he said. My 12 started out just great, but I've developed the "tick" at 2700 miles. It's most definitely noticeable -- my hearing isn't that great and I can still hear it.

What's the latest on the dealer denials if I take it back and yell about it? Will they deny everything and make me wait for a CEL or just put a new head on without fighting too much?

From what I have read in the ticking threads, it depends on the dealer. Some will do everything by the book starting with a reflash. Others will cut to the chase and go right for the head.

I'll let you guys know tomorrow! I have the Main techs # at the dealer I used, I'll call and ask him what protocol is. I've heard there are TSB's attached to certain VIN#'s so maybe now they just cut to the chase and replace the head! I've been fuming all day about this! Not sure yet if I'm gonna even keep her... Maybe trade it in on a new vehicle for my wife... Then wait 6 months and order another one! Don't feel like I should pay for a tainted vehicle... I don't feel comfortable dumping Thousands of MOD dollars into a potential lemon... I'll post my results later tomorrow night
