Pcv valve?
#16
The PCV valve on the 5.4 is located in the intake manifold on the drivers side, behind and just below the throttle body. The only thing that connects to the valve cover is the PCV hose. The valve is heated and held in by two bolts and really only requires replacement if the heating element burns out. It's designed to not need regular service or replacement.
I have replaced the PCV those that goes from the drivers side valve cover towards the throttle body. It has 90 degree black ends that snap on with green clips to the nipples. That was about $40, but I got in in a few hours (and they are close by). I also replaced the vacuum hose to the brake master. I have cleaned the wires in the watchamacallit. I still keep getting the P1074. I disconected the battery for 5 min and stepped on the brake pedal before reconnecting.

Do the rest of the list need pre & post numbers as well? The parts guy didn't know what I was talking about, especially since he is not familiar with selling the peices seperately.
OK, just tried to google those part #'s and only 14A464 gets a hit and it shows up for a 4.0l SOHC. Does anone have the correct info' for the 5.4l?

Hi GoRacer! I have a P0171 code. some f150 members told me check the PCV in order to check leacks but all of them told me the PCV is located on the passanger side but i can't find anything that side. Is it located in the drivers side as Quintin told you? is that a PCV attached with 2 screws to the plenum? or where is located?
Thanks for your help. Hope you alreaday fix your problem.

Is this the PCV?
Is this the PCV? I think it's the blue side. but what is in the yellow side of the picture? I tried to disasembly but the screws are damaged. i can't take apart and its a little loose.
How can i check a leacking point in these hose, and both terminals?
Are any of these parts serviceable? the truck has 189,000 miles and never replaced before.
Thanks in advance for your help.

This picture is what is underneath the yellow circle you have posted, I thought it was the PCV valve but I can blow through it on both sides so it is not a check valve (unless mine is shot). I pulled it off and cleaned it but I am not sure what it does. It has the harness connected to it. Does anyone know anything about these check valves??

what your looking at is the IMCV or intake manifold crankcase vent valve as my ford tech calls it. There are also 2 valves, one on the valve cover which is nothing more than a check valve, then the IMCV which is heated and PCM monitored for current draw needed to reach set temp. if it requires to much current the PCM will indicate it is malfunctioning. the IMCV can be cleaned fwiw, but only with something that leaves no residue on the heater element.
