See my thread about cam belt checks. My new belt is 6000 mls od now and no wear at all( watch out for the tensioner retaining bolt however. She is also a little bit ratllely at Rickover but if the S and S holds together I'm a happy man also.
Morgan did of course go to four cylinders and very rapidly add that extra wheel. I've been driving the old girl all through Xmas and will be taking her to work tommorow. Still can't get enough.
