Ok I did some more research on the mystery PCV. In late 2006 Dodge changed the location of the PCV on the 4.7 from the filler neck to the back of the drivers side valve head.
If you look at the emissions diagram on the hood of your Dakota it will show you the location. It is the blue item at the top of the picture. (see picture)

Usually back to the throttle body plenum or air cleaner.

PVC TBS Change
Dodge came out with a Service Bulletin 25-002-08 in May of 2008 to stop the moisture from freezing in the PCV plumbing during extreme low temperatures. The Bulletin replaces the existing PCV/Oil Fill Housing with a new Fill Housing without the the PCV port. The new and much larger PCV valve is located on the drivers side just aft of the valve cover and it is threaded right into the engine block. They also replace the upper half of the air box and do some rerouting of the tubing. So check out Dodge Service Bulletin 25-002-08
