New PVC valve

Changed the old one out today and man was it a mess. It barely rattled when I shook it and I had a bunch of crude oil built up on the end of the splitter at the other end of the hose. It took longer to get to the misc parts off that were in the way than it did to switch it out.

Getting quicker with the TMIC removal/install though got it down to 5mins now.

You know I don't think I have ever replaced mine. I swapped a bunch of parts over from the old motor to this one. Huh maybe I should get around to checking that out this week...It's always a hassle getting to stuff on these cars, but them more you do it the quicker you get at it. I have plug changes down to about 15mins.

The dealership charges for 2.3hrs labor to change plugs....crazy in my book. Thanks for the links I always like seeing pictures more so than reading about what to do...

Not sure, but a buddy of mine works at the local dealership and tells me some of the horror stories of labor bills that he has seen there.

well you have to being blow through so unmetered air doesnt get into the mani, but i think anyone could do it.

underboost the PCV is forced shut by the mani so boost doesnt get into the crankcase and inlet, but blow by is building in the crankcase because a little will pass the rings. all that blow by then gets forced out of the crankcase and sucked into the inlet by the turbo. when going for power i really dont want that blow by crap going through my inlet and turbo etc. now you could leave the PCV in place but just cap the inlet return and hook that line to a catch can and all would be good. however i like simplicity and while im sure no blow by is being produced under vacuum i still dont like the chance of my mani seeing that crap. before i removed everything from the inlet and stuff i did remove my mani and the heads did have a nasty build up of sticky ass crap. from mile 1 my 2011 wrx will have everything pulled from the intake system so only 100% air gets in.
