I think that moisture comes from blow by gases of combustion and travels up the distributor shaft and condenses inside the cap. Instead of replacing the cap, I would simply open it up and let the warmth of the parked engine dry things out. Or aim spot light at it over night. You might also check to see that your PCV valves are clear and allow crankcase moisture to escape before it travels past the seal on the distributor shaft and into your distributor. Maybe the seal could be replaced if it's real bad.
