Timing chain marks

[wallsballs]

Hi we have a Yaris its year is 2000 and its a 1.0

We are doing the timing chain as its is lose but we cant find the timing chain marks, we have looked on Autodata they say the marks are on the chain but we have looked at the whole chain and there are no marks on it. We have the static marks on the cylinder head but non on the chain or even know if they are on the chain.

If anyone knows where the marks are that would be great.

Thanks Adam
