hi

A relative has a 2001 Polo with 20k miles.  It has the 1.4 8v engine.
We're unclear whether the cam belt needs to be changed.

The service log book just mentions renewing the belt every 60k miles.
But I've read here and elsewhere that the plastic tensioner is prone
to failure on 16v engines and perhaps the belt should be changed at
40k miles or 4 years.

Can anyone tell me whether the 8v engine is similarly prone to belt
failures and whether it uses plastic belt tensioner?

cheers
