Can anyone tell me what all the vacuum hoses other than the EGR stuff and the cold start flap thing are for? mine are mostly perished and i've started blocking them off as they leak and I can't work out where they all go.
Is it okay to remove all the junk there?? hoses, those valve things etc...??
or if it's required does anyone have a photo of a complete set-up with everything in it's proper place?
