Best all ways be to change a Cam belt 10.00km before the manual of 60.000km and replace crank cambelt sprocket as well it wheres out and can let the cambelt jump teeth beding valves
I don't agree with what you wrote there, but as with all forums everyone is entitled to express their opinion.
Sorry for typo its 10.000km before 60.000km reason motor company does not build motor to last for ever. Ihave change mine and now 430.000km on the clock
