It sounds like you either have air in the line, or a leaking slave cylinder.
If the oil level in the master cylinder does not go down, it's the former.
Just need to bleed it. I use a syringe from the feed store (without needle). Use a small piece of PVC hose on the end, put it on the bleeder nipple and push it up to the master cylinder.
If the oil level is dropping, and needs replenishing, the o-ring on the slave cyl piston needs replacing. If you have leakage around the slave, the sealing o-ring on the perimeter is bad.
