i believe this is quite a common annoyance, basically the breather pipe (one with the very brittle plastic clip) keeps coming away as the plastic clip was broken. i keep trying to tape it on but it keeps coming away.
not sure what others have done about this, as the same issue will happen even if i bought another part as mechanics who service seem to end up breaking the clip at some point.
also, if breather pipe does come away so is not attached, what problems if any does this cause - ive heard the engine area being a bit louder (almost like a rattle as you put foot down) but can it damage anything, or loe mpg.
any help is greatly appreciated.
