indirocz28 From what I have been reading and researching about so far is that the 2014MY filter change is not something that is able to be retrofitted on to the 2012/2013MY 3.6L engines.
11-08-2013 12:24 AM
Lusus_Naturae Now that the '14 is out, has anybody looked at what it would take to change a '12 or '13 to the '14 filter? How many parts are different and would you even want to do it? (aside from warranty issues due to changing it)
11-07-2013 08:53 PM
c_caz I test drove a few 2013s before getting my 2014. One of the 2013s was noisy as hell as at startup for about 5 seconds. The other completely quiet. My 2014? Also completely quiet. I think some of the 13s are louder and some quiet.

LMT Rubi I wish my 2013 JKR isn't affected by this!!

VERY POOR SAD ENGINEERING..............
IIRC the 2014 filter was redesigned and has a ADV. I'd like to hear a 2102 that sat for two days start up next to a 2014 sitting for the same amount of time with the newly designed oil filter.

i82much Haven't heard much about '13 that have gotten a head replaced, any more news on this? Seems to be fairly isolated? Or just wishful thinking on my part ...

2013JKBulldog Sounds like it needs a constant electrical oil pump

Jeep_88 Just took my 2013 JKUR in at 24K as it has appeared louder than it did when new, especially in my parakade at work where it echos off the wall. I compared the noise to youtube vidoes I found regarding the Pentastar tick and it sounded the same to me, especially when I recorded the noise and listened to both on my computer. After taking it to the dealership today they told me that the noise is from the injectors and there's nothing to worry about, many people have done the same thing apparently so we'll see if I end up having issues down the line. As per the comment above the Pentastar is loud on startup, it sounds the same as it does after you change the oil every startup, like the motor is running without oil for the first few seconds, I guess that's why approximately 50% of engine wear is from engine start-up from what I've heard from mechanics.

Ceccacci I sat out the 2012's hoping the problem would be fixed, but bought one of the first 2013's back in August. Over 13K miles on it now, no problems. Yet. But then, I was nervous enough about all the reported problems to pay $2K for the lifetime warranty... so I'm not really worried about it anymore. If it breaks, I'll be inconvenienced, but they'll fix it.

Motoman01 Just got my 2012 Wrangler Unlimited (early production 2012 model) back from the dealer. About 6 weeks ago I got a check engine light I took it in and it showed a misfire on the # 4 cylinder. They uploaded a new program to the ECU, they drove it for 27 miles -- no codes. We took it home and about two days later the light came back on -- Took it back and it had a # 4 Cylinder mifre code again. They replaced the spark plug, plug wire, and coil -- didn't fix it so they put a cylinder head on order -- the cylinder heads were on national back order. After waiting a month the head came in and they replaced it. When they pulled the original head one of the valves was stuck part way open. My left cylinder head was always somewhat noisier than the right side -- so I always had the concern. Since they replaced it the left side is as quiet as the right side. Keeping my fingers crossed now. It has just under 16K miles on it.

7500/1,300,000 = 0.5769%

The article said 7,500 out of all applications (200s, 300s...) of 1.3 million engines, not just JKs.
I can't check their 7,500 count, but their division isn't that bad...

Even one JK is inexcusable (especially if it's mine), but 7,500 JKs would be a LOT.

At start up there is a lag time for that filter to fill back up, therefore we hear some tick/rattle on start up. My 2013 does it, but it is very minor to some that I have driven. I road tested about 6 different Wranglers at different Dealers, before buying mine. They all make this noise, some are a little loader than others, mine is one of the quieter ones, but it still does it. IT JUST BLOWS MY MIND THAT CHRYSLER WOULD NOT HAVE ENGINEERED A ADBV VALVE IN OUR CURRENT PRODUCTION ENGINES. I SENT A E-MAIL THROUGH THEIR TECH SERVICE DEPARTMENT AND ASKED AS TO WHY AND THEY NEVER RESPONDED BACK TO ME.
This is just a oil starvation sound that we are hearing at start up, and to the best of my knowledge has nothing to do with the cylinder head issue.
IF I AM WRONG AND THERE IS A ADBV IN THE 3.6 THEN PLEASE LET ME KNOW WHERE IT IS AT IN THE ENGINE................

I'm not sure I agree with you. My 2006 Infiniti G35X purred like a kitten 100% of the time till the moment I sold her at 47k miles. That motor was music to the ears. I've never heard a motor make as many odd & disturbing noises as the Pentastar, and those noises begin at startup with the fuel starvation rattle

While the 2012 defective head is very real, it seems that mass hysteria is our real problem now.
Legit, you aren't going to believe this and are probably going to think that old OD is just making this up, so let me assure you that I am not.
I just double checked my manufacturing date of my 2013 on my drivers door Feb 13, scary, because they were on the line the same day! The odds of that happening in Vegas has to be way out there. Mine also makes some noise at start up!

HK_Runner Nothing Fiat about it either way.

dale 3 My 2 cents....Think about it?
Im confused, does chrysler still own jeep or does fiat own jeep now? - Yahoo! Answers
05-19-2013 08:21 PM
HK_Runner They are saying 1% SO FAR. I am thinking that 1% will keep going up. I wish they would come out and tell us exactly what causes this. Sounds like ambiguous and shady BS to avoid a recall or something. Great...my first new American vehicle.
05-19-2013 12:16 PM
CARDER001 This is so disappointing. I was so proud to buy an American Made Vehicle again, even though a lot of parts are made else where.

After the initial valve rattle at start up, mine has a mild ticking sound, but I think, I hope, it's just sound coming from the fuel injectors.

I got the lifetime warranty so I will not complain unless it gets worse.
mine too. Build date Jan/2013

Not impossible, I'm just not seeing it right now.

I also don't trust dealers very well, our good dealer told us we had an oil leak coming from the oil pan in the Sebring. They gave us a $500 bill to do it because of the labor required. The leak wasn't bad, so I got it up on the lift to really look at it (the only reason I really like that dealer, I'm allowed in the shop to look at my vehicle). I poke around under there and find the oil pan leak is a oil sensor leaking behind a shield and running along the oil pan lip. I take it home, buy the part for $25, and take it over to my friend that has a lift and do it myself. Your dealer is only as good as the techs working there.
I kinda agree on this one. 580 miles is a record for a misfire CEL. I suspect something else was faulty and they had a knee-jerk head replacement reaction instead of checking the plugs/injectors etc.

So yes I guess it has spilled way over into the 2013 model year.

HRR1 How did you get that picture? There are wires and connections in front of mine. All I can see is the _ _ 3000 at the bottom.
12-08-2012 10:52 PM
mjpjr45 Got mine in Sept, now has 2900 miles, and no ticking yet. I was never a Chrysler fan, but I am a bit impressed with this engine. It is surprisingly peppy. Just wish it had a bit more lower end torque.

you can see it if you put your chin on the driver's side fender and look past the steering column.
It's 3002g
