Don't start worrying over the condition of your camblet. If worst does happen and it snaps it does no damage at all on the C20NE engine as it is classed as a "SAFE" engine. I.e the pistons don't hit the valves in the event of a failure.
Trust me, been there, done that.
If you want your timing belt changing I'll pop down to Alex's place and do It for you.
I'll even pick you the belt up at trade price.

(No forgetting, there is 2 different ones for the 2.0 ltr Depending on which water pump fitted)
Lets get sunday out of the way and we will sort it out.
