For clarification....here are the pcv diagrams for 2005 - 2007 4.7l (and 3.7l) Dakotas:


This is the 2005 "original" (#3 is the tube that goes from the back of the intake to the PCV on the oil filler tube)



This is the 2006-2007 "Revised" PCV (#6 is the pcv screwed on the back of the Driver's side head, #7 being the tube going to the back of the intake to the PCV


So, what are we talking about?

 

I did a boost and vacuum leak check, Im good there. At idle, I sit anywhere between -20 to -24 psi. Im going to do the catch can, just so theres not sludge shooting everywhere. Im going to run two lines from the filter pre turbo(one to the fresh air hose and one to the exit side of the catch can) and Im going to run a line from the pcv to the input of the catch can. This will atleast make the pcv system run accurately and clean up the engine bay. Im in the progress of diagnosing the a/f problem with my tuner, hemifever. It's just running insanely rich, rich isnt bad, but this is rich rich, ha. Just going to go from there.
