Steve - any updates? How does your fluid look?
I just received/installed another clutch master (my 3rd in a year), and flushed the line. The current part does look better (normal) for the bottle to body joint and is still dry after a month!!!! However, the fluid is turning dark after less than 100 miles. I could see hints of darkening after the first 20 miles of driving.
Some say it does not matter, but to me it is a sign of something happening with the seals??!! I'll drive mine a bit more and empty/refill the bottle and see if it continues to pollute the fluid.
