PCV Valve replacement should take about 5 minutes on most cars, sadly that's not the case on turbo Subaru's. Set aside about an hour...
It's hidden under the intercooler and intake manifold
Unplug all of the intercooler parts
After the IC is out you will gain access to the PCV valve assembly
Unplug the intake manifold end
And start undoing the pesky unique clamps that are impossible to put back on.
PCV valve out, notice the white goo, the whole valve is covered in it, which caused the valve to stick open/closed. Not 100% sure on what causes the white goo, someone said that it might be from water evaporating from too much city driving.
Engine side looked mostly clean
Got a new PCV valve from eBay, this one is for the Forester XT, it was $10 shipped so hard to beat. Aftermarket metal valve only (no plastic assembly) is $12!
Subaru OEM parts are VERY well priced.
Here is the clips and how they should work, good luck getting them to work...
New valve installed
I gave up trying to reuse the two clamps and just used zip ties.
EDIT: Finally got the special tool and reclamped it
Finally installed everything and tightened all of the intercooler clamps down. I noticed the throttle body one was rather too loose.
