cam belt on 300 tdi

(1/3) > >>

camaroneil:
just wondering,
when the cam belt snaps on a 300 tdi does it do any damage?
natt

TimM:
The cambelt operates the cam, which opens and closes the valves.....

If it breakes it can leave a valve 'open', and if the engine is still running (being turned by the gearbox), the piston head can 'clout' the valve and put it through the head and even the bonnet if hit hard enough.

Is that enough damage to put you off breaking one?

camaroneil:
oh well,
i know some cars don't do any damage but they are few and far between,
was hoping this was gonna be one,
had the new belt for 6 months, just can't be @rsed to do it,
thanks,

I can't think of any  :?

If you break other belts there will be no damage, you would just loose something such as power steering, or the alternator, or air-con*

But a CAMbelt I would have thought was disasterous on any vehicle.


*I'm talking in general here not Discovery specific

Wanderer:
Some engines have a recess in the piston where a valve would never make contact with the piston.
