cam belt change on a selespeed TS
i just had my cam belt changed as the log book stated that it had gone 50000kms or 3 and a half years since its last change (it has now done 90000kms). interestingly my independent said that he pulled out original manufacture idlers and tensioners. apparently the idler is plastic and what he has put in is metal. the replacement idler has been metal for quite some time he said. but the cam belt was changed.
so my log book says the cam belt has been changed at 40000kms and it looks like that is all they did. so i called alfa brisbane where it was done and they have told me they replaced the lot (cam and balance belts, idlers, tensioners) as part of a 60000km service.
what or who should i believe? did anybody ever supply plastic idlers?
