clutch oil leak

[Hondaman4ever]

Noticed the oil level in the clutch oil reservoir keeps going down slowly over time and today I took a look at the firewall (inside the car where the clutch pedal is) and saw oil leaking down the firewall. So obviously there's a leak and I'm wondering what part that is and if it's something complicated or hard to fix by myself.
Thanks.

Oh yeah. It's a '98 Civic.

Replace the clutch master cylinder.

Ok. Thanks, Ron. Would an after market part be fine? I'm sure a Honda one would cost double or triple the price especially here.
