2007 jeep liberty 4x4 (176000 miles)ticking noise

[bafulle]

Need some help here if possible. I have a 2007 jeep liberty that's making a slight ticking noise at idle that gets quieter the higher the speed I go(link of video at idle in park below). I'm wondering if this could be a lifter tick or something else? A couple of things I have noticed are when the car is running and in park, it is the quietest, when idol it gets louder, and when the AC is on its the loudest. Also it is hard to tell, but it sounds to me like it's coming from lower like down at the bottom of the engine. If anyone else has had this problem or any advice it would be greatly appreciated.

could be an exhaust leak. mine developed a tick earlier this year, also from the driver's side. it's not a lifter tick I know that. it sounds more like exhaust. I need to get under there and see if a bolt/stud broke, or if it pushed the gasket out.
