[QUOTE="SteveF, post: 80201, member: 3111"] Following on from this thread, I've spent a bit of time measuring the list on my C Rapide. The previous owner claimed that it had 'Lighting Cams', whatever that means. Once again, I've found nonsense in this engine. The lift on both inlet valves is about 9.4 mm. The exhaust lift is about 9.1 mm on one cylinder and about 8.5 on the other. Clearly one of them is either not a Lightning cam or is worn out. When I stripped the engine all the cams look to be in pretty good condition so I can only assume one of them doesn't belong. I'm guessing it's the one with the smaller lift. Can anyone point me at a table of lift values for the different cams so I can decide what to do. Cheers - Steve [/QUOTE]
