Need some insight. Had a clutch leak, and figured it was the fitting at my aux bleeder fitting at the slave. Dropped the tranny and found the aux bleeder hose must of been touching the exhaust and burnt a small hole in it. That explains the leak and loosing pressure. But what's up with all the crap in the bell housing? I know i have a coolant leak near the water pump and it does drip and get on the oil pan, which makes it's way to the bottom of the bell housing (doubt that has anything to do with it), and doesn't seem like my main rear seal is leaking. Could my slave be leaking? The aux bleeder line was elevated, so maybe as it would leak, it would travel down the line into the bell housing? Let me know your thoughts. Looks like crusty residue.
















It does seem like some oil got past the main rear seal in this picture, but it must be a slow leak as the oil level has not moved.

 

you will need to pull the clutch/FW to see if the RMS is a "source" of a leak

it is possible if the burnt line was pointing back downhill into the bellhousing that fluid would then be thrown everywhere inside bell housing

either, you need to resolve as fluid of any kind will contaminate the clutch disc

from this side of the internet it does not look like in your pics the TO/Slave bearing is leaking
