clutch slave leak

[mark81]

flushed fluids @ 50k miles noticed then clutch fluid was low. now 4 months and 7k miles later fluid is at bottom of sight window again. I can't see any leaks around master cylinder.  could the fluid be leaking into the crankcase and mixing with oil or is the slave separated from the oil?

If it is leaking out of the slave cylinder, you will probably notice it below the slave cylinder on the clutch cover.  Might even take the paint off of the cover. I do not think it would leak inside the cover and contaminate the oil.

If your oil seal is shot, then yes. Rebuild your slave cylinder and just to be safe, change your oil.

The flexible parts of the line can start to 'sweat' fluid, and the connection points can leak, too. Probably under the tank, of course. Do you know when/if the line has been replaced? They do fail with age.

Thanks. K&L rebuild kit quality?

I would rebuild the slave and master.  Put in a speed bleeder.....it will make things much easier once it's all back together.
Note that sometimes air bubbles develop right where the line connects to the master...this can make bleeding very difficult.  Just crack the line to bleed the air out if needed.
