Pcv?

The original 4.7L V8 design had the PCV valve in the filler neck. However, there was a TSB to relocate it to the rear of the driver's side valve cover after there were complaints of moisture collecting in the PCV valve located on the filler neck and then freezing at cold temperatures.
The reason I figured this out is because I went to replace my wife's 2006 Durango's 4.7 PCV, only to discover it was not where it was supposed to be. After an exhausting search of the internet, found this TSB. Yes, it is for Dodge Rams, but it applies to the 4.7L V8, and I am pretty sure (can't find them anymore) there are equivalent TSBs for any Chrysler vehicles that came with the 4.7 before they made the drivers side valve cover the factory location. My wife's 2006 had it there from the factory, supposedly, so I am guessing the 2006 model year or there-abouts is when they made the change.
Beware, parts stores are clueless about this change/TSB, so they will still try to sell you the old PCV valve. Even my local Chrysler dealership tried to tell me I still had the old valve. I had to go to Rock Auto to find the right one. If you have the valve in the valve cover, here is the part:
AIRTEX / WELLS Part # 6P1279 {#53032925AC, PCV410}
And only $20 + shipping. I love Rock Auto.
