    On my 3rz I have 2x little check valves on my vacuum/emission system. (One blue one orange) Does anyone know which way they are supposed to go on?? I feel like I've removed them before and am not sure if I put them back in the correct direction or not.

    will upload a picture in a second.

    I think i may have just figured it out by looking at this picture… It seems like the open side (side that lets air through) should be towards the intake manifold so the intake system can suck air out/create a vacuum of whatever those vacuum lines go to. (if that makes any sense at all.. lol)
