My cousin will be doing the work, he's a good mechanic and goes to the rallies around the country working on a car for someone.well to settle your fears get the guy thats doing the cam belt kit to give the whole van a once over, couldn`t cost you more than 50 quid for an hour of his work, even get an estimate from him for labour if you get the parts to get her through a test...
if its not worth doing he`ll quickly tell you... if hes trustworthy that is..
Cheers anyway ae, your advice is always welcome.
