hi update on previous thread,my 2001 brava 1.2sx was broke by garage as they had put on head gasket the wrong the way round,{which they still deny}problem now is the cam shafts that were seized is their anyway to repair and unseize them or are they completley broke?if repairable how? and as the hydraulic lifters have just been placed in the boot can they go anywhere in the carrier or will they need replaced also ,can anyone suggest a good place to buy the valves that have been bent thanks
