2004 PCV valve replacement

Discussion in '2002 - 2005 Ford Thunderbird' started by 04tbirdjerry, Feb 12, 2019.

  1. I have bought two different pcv valves for my 04 bird, both times a mech told me it was wrong one. I went to Pep Boys this time, they said they don't carry one. I was told it's against firewall, driver side, off back cylinder. I can't even get my hand back there. Anyone know where it is, and where to get right part? I checked YouTube, only 1video and wasn't much help. So, Help!

    Folks, when you post to the forum, add the model year(s) of the car in the subject/title of your post. I just edited and added this.

    What is a "PCV" valve? My 04 manual shows one "Evaporative emission canister purge valve" and two "fuel vapor vent valves" and "one fuel filler pipe check valve" as parts of the Evaporative emission control system. I hope you meant the first as the others require removing the fuel tanks! The same manual shows the first item as the thing that looks like an oven knob on top located on the right side (drivers side) between the strut and the brake master cylinder. Three connections ( 1 electrical and two hose) point backward and are most likely the problem. I recommend removal of one plug and two hoses, cleaning and replacing them.

    Like cdintexas said. I did a search of my manual and could not find PCV valve.

  8. This could be very helpful. I am beginning to believe folks have been referencing "pcv" as a generic ventilation valve that should be replaced or cleaned. Thank you, I will pull and clean this as my next step to improve low idle.
  9. Sweet, let me check Rockauto. Thanks!
  10. I bought the last one Rockauto had, thanks again.
