I was wondering if you could help me out. I saw this picture that you linked - https://farm9.staticflickr.com/8652/16461064730_037d1ef7f4_b.jpg - and couldn't find that part on my car. I was looking near the pcv valve, and I just couldn't find it. This is what it looks like from the driver's side up near the throttle body on my car.
1 is the pcv valve (I think), 2 is the air-out hose (i hope). I was wondering where the green part in your picture is located, ish?
