My has done 92,000 miles and was wondering if I should get the chain changed. There is a noise when idling from the engine which can be described as tappety and I'm sure I read somewhere this is the point where you should change it.

Anyone have any experience of this? or advice.

Think it is advised to do it at 100k

Cheers watkja, think I'll get it done in the next few 1000 miles then.
