Help please timing marks 1.6 156

Hi I am a new member in need of some help!
I have 2001 156 1.6 the timing belt snapped and I have rebuilt the head my problem now is that I have no idea how to set the timing - is it the same as 2.0 ?
I have seen the diagram on this forum showing the marks on the belt but how will I know if the inlet cam is in the right position?
Any help would be great, Thanks guys

Get hold of a TDC gauge & camlocks - 'tippex' don't work on these engines

Have you changed the Valves and big end shells?

There is no such thing as timing marks on the TS as Jon says, you do need the cam locks which are different from the 2.0 ones, you shouldalso have to hand the belt tensioner tool too, otherwise you'll be taking the head off again soon.

Hi, Thanks for the replies, yes I have replaced all the valves and guides hoping to get away with the big end shells !
Would either of you guys mind explaining exactly how the cam locks work as I thought they were used to hold the cam position when timing is already correct as in a belt change.? would these help in my situation?
Thanks again for taking the time to help

The cam locks hold the cams into the correct position (with crank at TDC) so that the cambelt can be correctly tensioned - the cam sprockets are not tightened up at this stage - only after the belt tension is set.

TBH if you don't know what you are doing - and I'm not trying to belittle you here, just offering advice - then you are better to get someone who has done the job to show you how....otherwise you can get a whole lot of grief.

As for "getting away" with the big might, but there's at least a 50% chance in my experience that after a belt snap you'll have knocking big-ends within 2-3000 miles if the big end shells aren't changed. For £40 or so, to me its a no-brainer.....Your choice

My advice - change the shells now or you'll be changing the crank in the not too distant future..
