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.
