Rare cars you dont see anymore,

Sound like someone dragging a bag of spanners down a cobbled street??

Hi,

In Days of Yore, cars used side valve engines (presumably cos they were cheap). Posher cars used over-head (or even OISE) cos they were more powerful. Over-head cam engines were even more powerful, but Joe Public didn't like the clatter from the valve train, so they were mainly used on racing cars.

Then they invented the notched belt cam drive, and suddenly OHC engines could be made to run quietly ... with the downside that the cam belt needed frequent and expensive belt changes. Some petrol engines might survive a broken cam belt. but I doubt that any diesels will be that lucky.

So why did they fit quiet running belts onto clanky diesels?
