Re: Another ticking noise
Mine has had a slight ticking noise for 2 years and 41k miles and no CEL. Most noticeable in drive-thrus when it has a wall to bounce off of. Just standing next to it when running it isn't that bad. Runs good, mileage has stayed the same so I don't worry about it and figure it's just the injectors. If it was something bad it would have hit by now. Enjoy your Jeep, if it turns out to have the defective heads just let warranty take care of it.
