2007 Jeep Commander 3.7 PCV Valve Location?

Okay I am stumped... I am doing 30000 mile maintenance on my 2007 Jeep Commander with 3.7 L engine, and I cannot find the PCV Valve anywhere. I have always done my own maintenance on all my vehicles, and have never had this issue. I did some online research, and apparently on 05-06 models it was on the oil filler stem. That is not the case with the 2007. Let me know if you have found this tricky little devil.
