My car passed it's MOT today. It's done 93,000miles and hat it's cambelt changed at about 50,000miles when I bought it! Just one question does the Cambelt need to be changed again? My dad it should be done again at 80-90,000, and wondered whether this is right or not? Also how much would a head gasket be for a 1.6 16v 98S Reg Astra (x16xe engine i think!) be as mine is on the way out?
