The problem with bleeding the clutch hydraulic system is that, compared to a hydraulic brake, there is no real resistance when you pull the lever in.
The clutch slave cylinder is bolted to the left side of the engine, pushes a pushrod through to the clutch on the right side, like most Japanese hydraulic clutches. The slave cylinder can be unbolted at the 3 bolts, and there will be no leakage. If there is an external leak at the slave cylinder, it will not contaminate the engine oil - it will leak into the countershaft cover area.
When bleeding the system, I unbolt the clutch slave cylinder, and use a heavy duty c-clamp or a small vise to provide the resistance needed for bleeding it. That way you can develop that firm lever pressure. If you bleed it this way, and the lever is still mushy, the master cylinder may be leaking internally.
