Hi I need to change the PCV valve on my 2013 C-Max with 125k I bought the valve but it does not look like what i think is the original. I have searched and searched and have not found any pictures of the PCV on the motor or how to change it. Can someone enlighten me as i think this is really simple. I have attached a couple of pictures as reference. The new valve is pictured. Thanks

 

I know the motor is very dirty any suggestions? I hate putting a pressure washer into all the electrical connections.

It's behind the intake manifold.  Open the hood, take a flashlight, and shine it between the center of the intake manifold on the engine.  You should see it.  I don't see how you can get to it without removing the intake manifold.  I highlighted the PCV in yellow which shows up as green over the blue. :)

 

How do you know it needs replaced?

I'd ask a SA at the dealer and have them give a quote.  The SM says to get to the oil separator:

  1. Remove the following items:
    1. Refer to: Air Cleaner Intake Pipe (303-12 Intake Air Distribution and Filtering, Removal and Installation).
    2. Refer to: Air Cleaner Outlet Pipe (303-12 Intake Air Distribution and Filtering, Removal and Installation).
    3. Refer to: Air Cleaner (303-12 Intake Air Distribution and Filtering, Removal and Installation).
    4. Refer to: Cooling Fan Motor and Shroud

Then, there's maybe 20 various connections, ties and so forth around the intake manifold to disconnect.  The manifold is attached with 8 bolts.  The SM says the manifold gasket can be reused if not damaged. 

 

The air cleaner stuff is easy and maybe take 10 minutes.  The fan and shroud apparently requires something (maybe fan) to removed from underneath the car.  Probably easy with a lift - 10 minutes.  The various connections although a lot of them should be easy - 10 minutes.  Then it looks like the 8 bolts are easy to get to.    The question though is maybe there's shortcuts and one doesn't have to do all this.  Maybe one can get to the PVC from the sides of the manifold or bottom once by removing enough stuff  to access to PCV.

3 ideas:

 

A.This might be better left alone.

 

B.  Is there a way to get the engine to run when in Park?  I think so.  Maybe you need to draw down the HVB.  Anyway, assuming it can be done, remove the oil filler cap with the engine running, and put your hand near/over the opening.  Feel suction?  If so, then the PCV valve is working.

 

C.  Another idea is to remove the hose on the other end - with engine off  - make sure it is clear, spray a little carburetor cleaner (Gumout) or throttle plate cleaner down there - that might clean up what residue there is.   Then re-attach the hose and start the engine.  Don't spray too much at one time, as it will end up in the oil.  I'm sure a little would do no harm, but don't use the whole can!  Or do it immediately prior to an oil change.
