| is in 5ft/lb increments - speculating that your measurement was taken when the piston helix was at its full advance position. When you tested that torque, did you remove the anti-lash springs from the piston helix or were they complete units? Your X-axis is labeled spring force and those four points give the impression that you tested 4 different return springs. Is this a correct assumption? The Y axis just states "cam torque to activate VTC", does this mean the torque needed to make the piston move completely to its advanced state or for it to just come up off its stop? The one thing that throws me off is that if you just apply torque to the cam to try and make it force the piston back, it wont actually move because the anti-lash mechanism is producing a lot of initial locking friction.
