Good morning, I have a 2003 Ducato 2.8jtd, I have had a new clutch fitted which was fine, I notice that the clutch now starts to stay engaged, after a couple changes. On investigation it appears one of the o rings on the clutch pipe has disentagrated, tried a few different o rings, but either to big or won't seal. Does anybody know what size the o ring is or if it's available from fiat? Tia Tim
