Default Need help with hose routing!!

Ok so I pulled the intercooler off and made an attempt to put hose clamps around every hose running between my Crawford ver.2 aos, pcv system (under throttle body and on top of crankcase), white check valve connector, evap purge solenoid and valve, air line from my grimmspeed boost controller, bpv recirc hose, and whatever else I somehow missed and connecting them to their respective port locations on my Perrin turbo inlet hose. Iíve been up and down every possible thread, website, diagram possible but most links have pictures I canít see (photobucket issues) or the diagrams or pics donít have the answers regarding having the aos I have and how it deletes the pcv valve coming from under the throttle body and what to do with the port that the pcv valve hose and the white ďcheck valveĒ connector route to.. on top of that, I got pissed trying to figure everything out all the mess of the evap purge solenoid and valve that I pulled those off along with the hoses and I canít find a decent diagram that will help me put it all back together properly.. this all happened after the first attempt at putting hose clamps around all the hoses connected to the aos to make sure everything was leak free. After I did that I took the car out for a drive and got on it and the car hesitated badly under boost and I noticed I had more vacuum than before.

Car is an 04 sti btw cuz I know that does make a difference on a few of the routing issues I have.

Like I said, I have read countless posts, watched both Crawfordís and perrinís install videos and install instructions, watched multiple YouTube videos, read stickies for faq on these issues, and still canít find anything containing the combo aos/turbo inlet that I have along with the evap purge solenoid hoses, and the way to route all of these damn hoses properly lol

When I installed mine on my 2006 wrx, it was a pain in the butt, but the Crawford instructions were enough to get in installed properly. Did you buy yours new? It should have come with a plug for the intake manifold where you remove the PCV valve. The white check valve goes away too I think, but you have to pull the metal spade out of it and plug it into the gray connector. I could probably go take some pictures of how my purge valve crap is routed on my Forester XT if you want some help with that. Send me a PM if so.
