Missing hydraulic fluid

[tjclemens2]

Hello,

I recently got an E30 that had been sitting for 30-something years and in the process, I have been handling all the little issues and one of those is that I continuously lose hydraulic fluid. I believe it has something to do with the clutch because the fluid stops draining after it reaches the point on the reservoir where the clutch fluid comes out. I replaced the slave cylinder a few months back so I know that's not the issue. Any thoughts on what it may be? I don't see any visible leaks so I'm puzzled, anything helps!

The rear seal on the master cylinder can leak into the brake booster. The clutch input cylinder can also leak and that would tend to leak inside the car.
