My drivers side carpet gets soaked with clutch fluid, what could be wrong?

 

cmc

 

Ragejed's right, that lovely clutch master cylinder. I'm having to replace mine in a week or so, fluid's not soaking the carpet but I can feel it on the piston and clutch engagement's kinda weird right now.

 

How much does a new one cost? what exactly is leaking, a seal or something. clutch feels pretty good though no problems except some rattlin in my tranny when clutch is not pressed in, think its a bearing or something. thanks alot guys
