No probs mate, glad i've managed to put your mind at rest. Mine went in Jan this year when it was frickin freezin - i must be softer than you though cause i lasted about a day before i decided i was too cold!
I guess it makes sense as they usually fail around 80k i think, the not overheating still remains a mystery though? Fingers crossed that solves it anyway and look on the bright side, you'll have another 60k before you need to change the cam belt again!
