The diesels don't take the same strain as a petrol. The petrols rev to 7,000 rpm, the diesels to 4,500/5,000 rpm so the belts last longer.
Without sounding a know it all, yes I knew that. But why run the risk regardless? Cambelts can still fail commonly on diesels, not only through wear, but also manufacturing defects too. It just seems stupid to me especially as belts are suppose to give less friction and noise and yet they are fitted to the noisiest engines....the diesels!!!
I would have thought though David that its relatively straight forward shoe horning a chain instead of a belt onto the exisiting engine lineup?

I think that's part of the point though. I guess the calculation is done on a risk assessment basis - how often does a belt fail on a diesel car?
I would add that I recently had a day with a chain driven 2.2JTS 159 and thought it was pretty damn good. But it sounded metallic and unpleasant when it was being booted and I guess that was down to the chain. I prefer the sound of my belt-driven 5-pot at full throttle anyday.
