Does my timing belt need changing?

My car has had a cam belt change at 60000 miles. Its has done 125000 miles since then and I am thinking it needs changing now. The service book is very vague on wether it was done after the 60000 miles.

Anyway got all the parts for the change and gave the car to my mechanic. He calls me up and tells me that the current belt looks new and there is no play in the rollers or tensioners. He says that car looks well maintained. He says that the current belt may have only done 20000 miles and changing it will be a waste of money.

I dont know what to do!!!

Can someone give me advice on this?

Thanks

Are you saying that to your knowledge it's done 125,000 miles since the last change?

If so I'd get it changed asap unless you can confirm it's been done very recently...

Was in my local indie the other day and he had an S3 sitting outside that he'd just finished re-building. The owner had decided to save some cash and not bother changing the belt when it was due. 10k later it snapped! Result = all 20 valves bent! shocked.gif

Think it might be worth just getting it done 169144-ok.gif

Is that possible? If the belt brakes then even after repeated turning of the starter/crank is it still possible to hammer the valves that are closed or partially closed? as the top end stays stationary confused.gif or is that because the mechanics don't stop instantaneously suicide.gif

It's possible I guess due to the inertia but pretty unlikely.

When it goes though it does mor damage to the engine than the values. Pistons get hit a sometimes break, the valve seat assembly can be ruined and depending on engine speed/stress the block itself can be compromised.

I may have picked him up wrongly - they'd certainly replaced all the valves, but whether they'd all actually been bent or whether some unbent ones had simply been replaced as a matter of course while it was stripped down anyway I don't know.

And yes, I believe there was quite a bit of damage other than just the valves.

I'll get a fuller answer next time I'm in... which will be quite soon as me front pads have gone... again!
