Did I wipe a lobe or ???

Reason why I asked is, in the past I had rockers wanting to "walk" sideways on the shafts, with a hydraulic application, it wont do it with a mechanical cause there's that moment of free play that exists. My point is, the use of the springs on the shafts instead of something solid in place of the spring you may want to consider. The hydraulic profile will always have a load and may want to take the easy way out by jacking stuff sideways.
