Guys,
Just been towed home tonight after my daily smoker breaking down
Anyway, it turns out the cambelts broken (well not actually broken but has slipped, the teeth have been worn away). Now I had EXACTLY the same thing happen in August and fitted a new belt.
Looking back through old paperwork the car has had two belts in 4k miles
What can be causing this ? first belt I can't comment of standard of installation but second was donr by a very trusted mechanic............ can't see what would cause two to fail so quickly ?
Only thing I thought of was maybe an incorrect cam/ crank pulley has been installed ?
At least there's no engine damage as they are a non interference design

Cracking engines these.
Only seen this happen once, on a 1.2 Nova, took about ten teeth off, didn't do it again.
All I can think of is not enough tension, and it slipped taking teeth with it.
Are you saying all teeth are worn down, or just a section where it's slipped?

Not sure about how many teeth are gone as haven't got it off yet.............. however the last time it happended the belt was in a mess all the way round
This most recent belt was fitted using the proper tensioning tool as well

i had the same problem on a xe engine so might be relevant for this, the belt kept sounding like it was coming loose and on inspection i found alot of teeth missing, it happened twice so i dealt into it more the second time and found someone had fitted the wrong water pump (square toothed type) and the pulleys and belt where round tooth, may be worth a look.

i.e. pump selection isn't important ?
