Well.....Friday sort of.

Well that makes little sense...mandating that brake fluids all be clear or
amber...Too bad, that was a handy way to tell if your brake fluid was
completely bled.
I normally don't put fluid into my Motive pressure bleeder either if I
am just bleeding a wheel or the clutch but since I was losing fluid and I
was working solo, I figured I didn't want to chance pumping air into the
system, so I put some fluid in the pressure bottle.
Just last night I found that sometime during changing the slave cylinder
I must have lost connectivity ito my O2 sensor...On my Inline VW motor the
O2 sensor wire is right there next to the clutch linkage, and mine has a
spliced connector. I just noticed my fuel consumption was increasing and
my coolant temperature is now lower than normal, indicating a very rich
mixture since my slave cylinder change......
Gotta crawl back under and check the wire to the sensor...
