The PCV valve on the RS is very simple to change. Very straight forward. Just take a pair of pliers and unscrew it. As far as changing it, I think subaru reccommends that you change it every 30k miles. I have about 46k on my car and haven't changed it yet . As long as you put your finger over the top of it and it clicks while the motor is running then it still works. But, a replacement valve is only like 10 bucks at the dealership so you might as well change it.

Hope this helps

very easy. just take the hose off, unscrew with wrench and then put the new one on tighten and put hose back on. your manusl tells about replacment. they are still good if you can shake it and here it rattle inside.

i just changed mine at 60k and the ball wasn't rattling too good, yet still moved...i'd say changing it around 45k, cause at 30 it was still fine but at 60 it wasn't moving too freely...

Take the hose off the PCV, unscrew it out of the intake manifold, attach the tube back to PCV and start the engine. You should be able to put your finger over the tip of the PCV and you should feel it sucking and clicking. Also, after removing the PCV, shake it. If it doens't rattle replace it, or do what I do, just clean it Carb/Throttle Body Cleaner. Just make sure that you don't overtighten it when putting it back in. The PVC does not bottom out with the intake manifold. Just take a look at how much of the threads are showing before you remove it. I put a little teflon tape on the PCV threads just for a little insurance of sealing.
