Daily overfill of CP3
1515 hrs. local -> Opened LLCV bypass valve one turn ccw -> less than 1 minute until liquid was evident out of the exhaust -> This is much different than has been recorded by Gerardo in the past few days (3 - 4 minutes) and is likely due to differences in our interpretations. 

Also, I routinely open the instrument air bowl drain valve at the pressure regulator near the LLCV actuator to verify that dry air is being supplied to the actuator -> Today this looks to have resulted in a disabling of the Start - Stop for this on the MEDM screen, i.e., the indicator bar went from green (START/enabled) to red (STOP/disabled).  I had to re-enable this.

I added a shim pack around CP3's LLCV valve stem with ~0.020" gap such that, in the event of a loss of instrument air pressure, the valve can now only stroke closed 0.020" from its current position.
