    air removal question

    So i removed the air pump and hoses as described here. I got a question that i cant find the answer to tho. As i pulled the big air hose off (the one with the tee fitting and goes from drivers side to passenger side) i noticed that a smaller hose came with it. (it was looped with a connector with the big hose) The smaller hose came from the drivers side from from a black nipple on top of the valve cover to a tee then two fittings on the passenger valve cover.(closer to the back of valve cover) Can someone please tell what these hoses are and what can i do with them? My car is a 98 ta

    on the Divertor valve selnoid.....there are 2 nipples for vacum hoses....one hose goes to the back of the manifold....the other hose goes to the divertor valve (that T thingy) you can just plug the one nipple to the DV....or remove the DVS and plug the nipple behind the manifold......your choice.......(pick plug the nipple on DVS)

    I actually dont think its related to the egr or air system, it happened to come out when i pulled on the air line running behind the engine. Pcv? Vaccuum lines?

    i dont recall a diverter solenoid on my car (keep in mind its a 98' it could be different than others) I cant also feel any nipples on the intake manifold. It seems to run from valve cove to valve cover...

    if its valve cover to valve cover your feeling the pcv valve lines, it starts on the drivers side valve cover, comes over to the passenger valve cover then comes up and ties into the the intake behind the t.b

    If it's connected to the TB, then yes you do. I ask for a pick because it would help clarify what you are looking at.

    your right steve, its a spongy line, but only to insulate the plastic prebent pipe inside of it. now that i have that figured out. what is the exact path for this hose/line?

    it is connected to a nipple behind the throttle body on the passenger side. and has little flat clips that connect into the manifold itself then a hose plugs into the nipple pointing towards the front of the car, then wraps around to the back of the intake and the plastic nipple will plug into the top right corner of the valve cover underneath the cowling
    i can get you a pic if needed. as my intake is off the car currently

    thats it!! your ends/connections look a little different, but the hose is identical.
