You've put the red/white valve around the wrong way, white part to the rear, red to the front.

The white check valve has small arrows on it. They should be pointing away/down from the left pipe that goes into the cam cover (looking at car left to right)
Hope this helps

Hey sorry to bring up an old post but im jst wondering.. Do you know why, in the first picture, your vacuum hoses coming from your cam discolored like that? and did it get worse?

I have a buddy whos 9-5 2.3 is doing the same thing. Its actually a little bit darker then yours, i think its even tacky but the rest is fine (crisp blue). its the 2 like yours (before and after the check valve) and his check valve is going in the correct direction.
