Rob, all,
OK, I don't recall what my clutch fluid looked like 4 months ago....not even sure that I checked! SOOOO I checked today, and my fluid is "dark brown" but not black. No goobers or floaty bits, just maple syrup!
We have a fairly humid environment here, and I wanna say that this is "normal" absorption of water???? I have a cast iron master clutch cyl also, which could be contributing. Now, I haven't flushed this since I worked on all of this some 2-3-4??? years ago....bad me...I know......barely drove the dang car..... vehicular abuse...!!!!
I will be suctioning this brown out, and replacing with new Castrol DOT4 before trip to Reno! Maybe flush out the cylinder if I get cooperation...... Will also check fluid in brake M/C which I DID flush completely when all 4 corners received new seals (stuck pistons!!!) and the M/C got a tear down only to find nothing amiss there!
I hope this helps.....!
Steve
