Corsa Intake Manifold
Hi Gurus
My brother has a Vauxhall/Opel Corsa and has had all sorts of issues. All have been fixed, except for one. There is a strange clunking, ticking noice and gets fast when revving the car. The last mechanic he's spoken to has said the intake manifold needs replacing and has been quoted over a grand for the work! I'm not convinced a new one is necessary, maybe repairing/refurbishing the existing one. Is this weekend job that can be done on our own, or does it require a mechanic? Can intake manifold parts be replaced with new ones?
