Absolutely no noise from my PentaJesus.

Though I come from subaru's, all their motors tick.

I haven't heard anything from mine, which was put together in October I believe. Although sub consciously I think I keep hearing one because of this thread

I figure I've got about 4 years and 10 months or 96,000 miles before it's really my problem.

Got the Jeep back today. Lifters were replaced. Sounds pretty much the same. Slightly discouraging. I will talk to the service rep next week and pick his brain.
I think I will try out my new video cam and document it.

Mine has been in the shop for this exact problem for a week. This is not an uncommon problem, though by no means 100% of the 2012s. My dealer has had this happen to 3 other jeeps before mine, and every time Chrysler just sent out a head assembly to be replace, which fixed the problem. In my case they decided to try replacing just the lifters, and as predicted it didn't solve the problem. So they shipped out a new head which should be installed on Monday.

What a Pentastar sounds like with new lifters.

My engine seems quiet, although I have not really listened. I'm used to engine noise - anyone who has owned an LS-based motor will know what I'm talking about.

If not then you probably shouldn't worry. Since that is mine, I'm a little worried that I there is something wrong with the engine in my $37,000 new jeep...
Offcamber that sux!!!

Your pics on JU were the motivation for me to run off and buy one almost identical to yours.

Seems our Jeeps are a little too much the same.

Let me know how it works out for ya as I wish you the best as well as the rest of the 2012 crowd.

My dealer has buried their head in the sand...

May try another dealer or drive it till it drops.

Wife wants to go to Glacier Nat'l Park for vacation this year. Hmmmm... would be a damn shame if the engine blew out about Missoula MT... wonder if she'd notice a 5.7L replacement under the hood.

Probably would notice the smile on my face and the hole in the check book..

Guy's thanks for keeping us all updated.

With these damn Jeeps I feel like a moth to a candle.

Swifty,
Sorry to hear that the lifter replacement did not take care of the noise, my Jeep has the same build date as yours
but with only 3700 miles and was wondering about how many miles you had on yours when you first noticed the noise. Thanks

Or you could look at my other posts in the 2012 check engine light thread. Which this thread should be linked to anyway...
http://www.jeepforum.com/forum/f96/2...51/index4.html

I feel like a broken record.
My Jeep got a new drivers side head, timing chain and cover. Drivers side exhaust manifold. Oh and new weather stripping for my water leak issue. All this after the P0302 (misfire #2 cylinder) code popped. And it was ticking away like a 80's era Mercedes diesel.

Thanks for the updated info Rivet.

Also did originally link the CEL thread in post #1 on this thread.

Felt that a new thread with a different title and pulling info from multiple sources might be of use.

Truly glad your ordeal is over
