Ok so I'm in the process of fitting the new belt, on the belts they have yellow lines on so you know the dot on the camshaft wheel lines up with the dot on the back plate for some reason my line is always a tooth out even though the dots line up as I'll show in a pic

 

As you can see here the yellow line on the left cam wheel lines up but the one on the right is a tooth out but you can see the two white dots line up

 

And again here

 

Also can't seem to get the belt on the auto tensioner as its to tight for some reason

Please help as its now really winding me up

Mine lined up perfectly with the notch in the oil pump, but i guess engines will differ slightly if they are only there as a reference.

So it looks like youve finally cracked it :thumbup: good luck with the rest of the rebuild.

Cheers thanks for your help everyone
