Okay, been searching everywhere on forum about pcv valves and not finding much info! I have an '05 5.4l and ordered a pcv valve for the truck but when it came I realized it was the wrong part, or so I think. Maybe I'm looking in the wrong place on the engine. Is the valve supposed to have an eletrical connection on it? The part that was shipped doesn't have one and doesn't look anything like what is on the truck where the valve is supposed to be. Anyone have any answers?

 

The PCV is located on top of the Intake Manifold. To remove the PCV valve, you will have to remove the fasteners securing the PCV valve, then the PCV.

 

Is the valve seperate from the peice that comes off the manifold?

 

Yes. The valve is heated and goes into the intake manifold on the driver's side of the engine. Follow the tube from the driver's side valve cover to the intake, and that's your PCV valve. Replace it every 100K miles or so.

 

Yeah I figured that was the right part, problem is nobody (and I mean nobody) lists that part for my truck. Not even the motor craft website. Any suggestions?

 

There isn't a PCV valve on 5.4l 3v engines. All it has is a restrictor in the drivers side valve cover.

 

Not according the 2004-2006 F150 Repair Manual.

 

if quinton says there is one then sure enough there is. he is a ford tech.

 

There's a PCV on the 3v 5.4, as Quintin said it's heated and requires very little service.

 

email me, I'll attatch pdf file from my ford service DVD. I've been meaning to change my soon too. BTW, how much was it?

 

I don't care if you believe me or not.
The service manual has been reprinted over and over again and hasn't been updated.
Do me a favor and pull the hose off the left valve cover, start the engine and see how much vacuum is at the hose.

 

What is that going to prove?

 

As of a month ago the pcv valve was not available as an aftermarket piece. To get one from ford it will cost about $300 because it is only available with the valve cover as a complete assembly. Wheres the smily for wtf ford?

 

If you take the hose off the valve cover and start the engine there will be full engine vacuum, not restricted by the PCV.

The only service the PCV will need is cleaning (because it's a restrictor and has no moving parts), but to do that you would have to pull the valve cover off.

By the way I use to do work for the engineers that did fleet durability testing on modular engines at Ford

 

You do know that the PCV on the 3v 5.4 is mounted in the intake manifold and not in the valve cover right?
