You've possibly got more than one thing going on there. It used to be fairly common to see old clutch MASTER cylinders work and then suddenly not work and then start working again later and that was found to be the old, spongy rubber cups in the MC folding and unfolding randomly. The situation was often exacerbated by dirty brake fluid with some water in it and there was no external leaking or loss of brake fluid.
Are you certain that the fluid leaking into the bell housing is brake fluid because the three small slave securing bolts will leak transmission oil if they aren't coated with thread sealant so maybe that's tranny lube? Of course they only leak when the transmission is active and oil is being flung high in the primary drive compartment. A really leaky slave would leak even when parked so you could dry it all up and see if there's leakage after it sits for while. Also, pump the clutch every hour or so without starting the engine.
Other sources of fluid (engine oil) in the bell housing are a leaky rear main seal or flywheel bolts that weren't coated with thread sealant. (The holes in the end of the crankshaft are bored all the way through.) You could also get transmission oil in there if a transmission rebuilder failed to put thread sealant on the two bolts that secure the primary chain tensioner. Also, it could be chipmunk piss but usually you'll see their nuts (or at least a little disturbed)?
