Be sure to suction as much fluid out of the servo as possible.  Supposedly,
one of the disadvantages of silicone fluid is that it turns to silica (sand)
when burned in the engine.

I used what amounts to a home-made air powered vacuum brake bleeder,
combined with a length of copper tubing to reach in through the MC hole and
suck the fluid out.

Assuming the servo isn't damaged (it's probably fine), a new MC should solve
the problem.  Sorry, can't help with which one to buy.  It's my
understanding that usually (tho perhaps not always), the seals are actually
compatible.  The "Don't use silicone" stickers are because the MC
manufacturer has not tested the overall system to ensure compatibility with
silicone (eg enough reserve capacity to overcome the compressibility of
silicone when it gets very hot).
