Timing question

[fixkick]

yes belts fail for
setting any tension, here.
twisting it inside out can, wreck it, (keep kids away and dog)
it really is not a tension!!
its on loose, my guess is that dinky spring ,nets out at 1 pound pressure? but Id bet the cam bias is the final say on set tension all 16v
the cams are live , in the setup full lash spec too..

so what is that spring really doing on belt ? easy
just keeping out all slack , nothing else !!
what it does is get that roller set so there is no looseness on the LEFT (facing belt) side.
calling it a tension'ing step is not really accurate wording (maybe there is none)
free clearance reduction step, sure.

this fact is why most engines now with VVT (J20b all have chains, no more cam jogging.
many tried and failed.
