    Z20LET Breather Hose Valve??

    Hi all,

    Sorry if this is the wrong place to post this issue but this is my first one!!

    Theres a weird dragging noise (sounds like air) coming from my car (Astra G SRI 2.0i Turbo - Z20LET) and after ive had a look it appears there is a valve(?) that has snapped, it appears to be connected to the breather hose, its just a little round valve and i need to find out what it is/called so i can order a new one!

    Checked all sorts of combinations of words in Google (as you do) and i cant find out what it is!

    Any help with this will be greatly appreciated.

    Cheers,

    Ashley

    Is it from the cam cover to the throttle body? because if it is that pipe they are very common on breaking, must be crap material or something. I just use a one valve from any vauxhall from the scrapyard on mine and it works fine (e.g brake vacuum hose one way valve). or you can buy the genuine one from vaux which is about a tenner. someone will post the part number for you.

    or and welcome to AOC

    Thanks for the fast reply!

    I think its from the cam cover to the intake pipe? i literally touched it and it fell off!! If anyone can get me a part number for it that would be awesome, i can take a picture of the broken valve if that helps?

    Thanks for the welcome too

    I swear that valve snaps on everybodys car

    Dont think it will be responsible for the whooshing noise though.

    The noise may not be related, i need to change O/S/F Wheel bearing to which may be causing it and im just being paranoid... :-S

    If anyone can tell me the name and / or part number for that valve though it would be great :P

    My car sounded rough ( a little like a whooshing rattley sound)when the water pump was on the way out, when removed bearig had gone and the belt guide had fell off one side of the toothed wheel. new cam belt, tensioners, rollers, auxillary belt and wter pump later, all if very very smooth and quiet. Stick your head down the rear of the cam belt cover to see if the sound is down near the wter pump.

    Thanks il give that a look when i get out of work! I found out the part is a 'Non return valve from the crank case breather hose to the air intake breather hose'. Called 3 different dealers and nobody stocks them, 2 - 3 days to get one in. If anyone has details for somewhere online that sells them that would be helpfull.

    Cheers

    I know this is an old thread but just been on google and this is exactly what i have where the pipe has snapped next to the white plastic bit. If anyone could give me a part number or where to get them from would be appreciated but im not going to vauxhall near me as there a waste of time.
