I have just replaced my headgasket with a group A item.

I have been told there is a mistake in the Ford technical manual on setting up the timing marks...

Could somebody just verify the correct marks to use on the bottom pulley and distributor drive pulley?.

Also when you set the rotor arm to the distributor mark - is it the centre of the arm to the mark or the leading edge?.

In the event of you not having a tensioning tool handy is a 90 degree twist on the longest section ok, or is there a better way?

I guess you can never be too carefull, so i am asking the resident experts!

Regards

Andy
