2003 F150 pcv valve location? Does it even have one?

I have a 4.2 V6 03 F150. I have searched the engine everywhere for the PCV valve. It's not on the valve cover anywhere as stated in Haynes manual and F150 forums, just oil breathers. Details of where this thing is (if it has one) would be much appreciated. A picture showing where it is would be super awesome. Haynes manual is worthless. Not very accurate with regards to engine layout. Reason I am searching, the truck threw a PO174 code, lean on bank 2. So I am guessing its not the O2 sensors, I cleaned the MAF sensor and K&N filter. So my next check was going to be the pcv valve and the elbow of the conection to see if there is a leak.
