Second cambelt change question

A while back I had my 147 1.6 53 plate belt changed under warranty due to a noisy tensioner at 34k miles. If all the cambelt trouble is down to rubbish belts and plastic tensioners, have alfa modified these bits so that they last the original intended time? ( like they did with rear suspension bushes) or am I stuck with a new belt every 2 years?

Re: Second cambelt change question

They did change the tensioners. The original ones were black plastic, the toothed part broke up on some cars, so they were changed for white plastic items. They still did not last the 72K miles so the lastest ones are now all metal.

I would still change at 36K or 3 years as the actual center bearing still appears to be the same in all versions, its just the material on the toothed part that has been changed.

Interestingly though the fixed tensioners are now plastic, when originally they were metal. I would have thought this would be a retrograde step, maybe someone knows better?

Re: Second cambelt change question

Newtensioners I got (tow in the last month) for the cam belt are metal (2.0 TS). The idler is still plastic.

Changed my Dad 1998 belt and replaced the metal idler with the plastic one (was going to leave the metal one but paranoid that the thing may sieze).

Tensioner on the balancer belt (2.0 TS only) remain plastic.

No sure why idler's are plastic.

Does anyone know which bits are the cause of premature failure, is it the tensioners, belts, idlers or mix?
