Amen brother. Loosening sprockets is what causes all the trouble, once you do then you can have partial tooth errors all over the place. Not loosening sprockets means you can only have full tooth errors which are much easier to see. The Ford procedure sets up the mechanic to have much more trouble to me. Then VCT confuses the issue even more.
The entire idea of the camtool is to get you merely right back where you were before you loosened sprockets to begin with. Silly.
If the timing belt teeth spacing was truly off virtually at all the maker would be out of business overnight. Those teeth have to be CLOSE to run at all well.
