I have a 2004, 307sw, 110HDi ,Diesel with 90K on the clock. The cam belt went the other day causing a little bit of damage. I have had an 'estimate' for the work and the most expensive thing on the list (except for the labour at about £700) is the valvelifters. I need 16 of these at £14 each. Is this about right? Headset £155 Replacement cambelt kit £130 Cheers Lenny
