Here's another method that might work without damaging the piston: Put
the MC in the freezer for several hours, remove it and warm it up
rapidly with hot water or even a torch. Repeat this several times.
This should be more effective if the piston is made of a different metal
than the MC body because they will have different coefficients of
expansion.
What this does is to break loose the corrosion bond which is what
usually causes the piston to be "frozen" in the bore.
