Piman, what makes you think there is air in your master cylinder? It appears that you disconnected the slave from the trans and let it hang by the hydraulic line while doing some engine work. If you didn't open the bleeder or remove the master cylinder, there shouldn't be air anywhere in the system, as it is a closed system. I did the same thing when I pulled my trans and just reattached the slave without bleeding the system. Everything worked fine, just as it did before I unbolted the slave from the transmission.

Was your pedal spongy? Was the clutch failing to completely disengage? What symptoms were showing thated you to believe that you needed to bleed your clutch hydraulics?
