Paul Workman · 05-26-2017

The critical cam timing factor, far as chain tension goes, is the chain length between the cam and secondary sprockets - on the tension side of the chain. So, as long as there is enough tension applied sufficient to remove any (practical) droop between those sprockets, then "enough is enough" and more (tension) is superfluous where establishing timing is concerned.

Beyond setting the initial cam phasing, the tensioner is relegated to managing the chain slack.

Other factors to change that critical length include subsequent chain wear or sprocket wear, etc., resulting in changes in cam phase changing over time.
