You dont even have to remove the IC to see it, just look at the gap thats right infront of the turbo. Look down in there and you'll see the PCV. Someone on here said that Subaru made this part so that it does not need to be changed out anymomre, dont know about that. Fromm my understanding they always have to be changed out on cars cause of the buildup they get after so long. Check it out, hope it helps you guys out. paid 12$ or so.



    Can you give us 04 wrx owners the part numbers for this piece? Thanks.

    FWIW to the 06-07 owners.....went to the dealership and they had no part # for the PCV (the parts guys are good guys too I knowem). Talked to my tuner on friday and he said that they really weren't an issue on the 2.5L because the system is routed differently.

    If the PCV comes with permanent band type hose clamps, perhaps those dealership folks saying that the PCV is a non-serviceable part were correct.

    The Knack. It's a rare condition characterized by an extreme intuition about all things mechanical and electrical ... and utter social ineptitude.

    This is great, it's the exact same as my 05... I'm trying to change it now actually, had to hop online to see if I can figure out why I'm stuck sorta... those clamp/crimp things, those are weird to me. Unlike anything else on the car really, and I don't know how they come off... because that PCV valve doesn't just screw out really lol

    TOOLS needed:
    19mm wrench
    12mm wrench/socket
    10mm wrench
    flathead screwdriver
    and some patients
    Instructions are nice and pictures are excellent. A couple questions.
    1. What is the year of the WRX?
    2. This PCV valve looks different than the factory one. The factory appears to have two parts: a metal PCV valve and a plastic body with two ports.

    I own a 2005 WRX with 50,000 and considering replacing the PCV valve, and clean MAF sensor/ Intake manifold/intercooler. Also, can I clean the intake manifold with the intercooler removed and run seafoam through the BOV valve hose? Any links for the things I want to do is appreciatted. thanks.
