ive been having problems with my clutch these days. i replaced my slave cyl a while back, but i cant get my master off.

its hard to shift from 1 - 2 - 3 at times so i thought i'd bleed the lines. i bled the lines... the fluid that came out into the glass container i used was all dirty. a dark smoke like stuff came out as the oil came out as well. why is that? is it normal... or just really dirty?

after i bled the lines its a LITTLE better but still a pain.
hopefully the solution is to replace the master cyl but the line going into the master cyl is stuck. i have been blasting it with pb blaster the past few days. still stuck. ive tried using a flare nut wrench.... no luck. slowly starting to round off the nut.

any suggestions?
