My 07 JKU burns about a quart every 1,200 miles. It ticks all the time, I have the lifter clatter. You name it, my engine probably makes that noise.
It all started at about 20,000 miles for me. I am now at 49,000 miles and the engine is still going strong with all the ticks. I will drive the engine until it blows up and then figure it out from there.
My father-in-law has an older Jeep GC. It does all of the same ticks and clatters as mine. That thing now has over 200k on it and still goes strong.
I hope my engine doesn't last that long. I want a hemi.

Yeah, the woes of the 3.8
Yeah, I had a 2007 Rubicon with manual trans, I bought it with about 10K miles and traded it in with 38K miles, it burned a little oil but not a lot, particularly after long road trips. The bigger problem was the gasoline overflowing out the filler neck. A few letters and video footage of it happening sent to the CSPC resulted in a TSB, but I traded it in at that point since the dealership "couldn't re-create the problem".
I traded that one in for a 2010 Rubicon, new with no miles which I now have 24K miles and it burns just a tiny bit of oil. It seems to burn "faster" when I go longer than 2-3k between service intervals. (I usually change every 3K, I personally don't believe in going 4-7K between oil changes). I had a discussion with the dealership about the oil burning and the official Jeep policy is "they do not consider it an issue until the consumption is greater than one quart per 1000 miles". I am tempted to send another letter to the CSPC about this since if you keep up burning oil like this you will clog your catalytic converter, and burning oil like this can't possibly be good for the environment or emissions. If you don't check it regularly and roast the engine, this sadly is not covered under warranty. You best bet for starters may be to get a "second opinion" from another dealership, if they say the same, you may have to just bite the bullet on this one and check the oil regularly with the new motor.
I myself am debating to just let it go and replace it with a hemi swap once the time comes, but my situation and "Jeep build up" may be different than others on this thread.
The other drag is that you can't replace this motor with the new Pentastar without additional extensive changes. Sorry for the bad news.

Sorry to hear that.....The JK forum here is FULL of threads about the 3.8L using oil and those issues.
Were you able to drive the Jeep home ? If so and it's full of oil and drivable I would get other bids for the fix....Might be if you have kept it full of oil and it hasn't run dry at anytime.. There may be another problem...second opinions are always good.
"Ticking" doesn't sound like a crankshaft or rod bearing problem....Usually Ticking is in the Valvetrain..... "THUMPING" , and HAMMERING usually is indication of Crank and Rod issues from low oil.
Good luck here , I hope you can resolve the issue... "BH"
PS: I have a 07 JKU, 3.8L It uses oil , "woods are full of em !!"...

Ticking noise = new engine?
Took the 2007 Wrangler into Beaverton Jeep to check the ticking noise I was hearing and they told me I need a new engine. Apparently there was no oil(?) in the engine yet my pressure was good, no engine light and no heat issue. This Jeep only has 45,000 miles. It is my DD. They also told me it won't be covered under the warranty or the extended warranty for that matter. Anyone have any experience with this dealership? Not sure itís worth the $5800 to replace the motor. Any suggestions, advise or help would be appreciated.
