I was thinking of doing a DIY cam belt change on my 456 - belts are original and mileage is 15,000. Unlike my old TR where the engine had to be removed, shouldn't the 456 belts be easy to change? There's quite a bit of room in there. Has anybody done this? I think it's pretty unnecessary to do all of the other 30k stuff, I just want to change the belts due to age. If I pull the old belts off and put the new ones on with everything in the same position, I won't have to worry about TDC pistons, etc. right? My only real concern is getting the correct tension. I'm 300 miles from the nearest Ferrari mechanic and bored this winter so I'd like to try. Any recommendations on where to buy the belts?
