Is it when you start it when motor is cold? My WK2 penstar engine did this daily... went away after a few seconds and was told its normal

I know of some defective heads that people have had but that noise is really loud. There's a very long thread over on jeepforum.com about it.

Cam phasers constantly adjusting and evap solenoid is very loud. Mine does it as well. If yours was built prior to 01/24/12 take it in to the dealer for a PCM update.
