Alan,

Running copious amounts of fluid through the system does NOT guarantee
that all of the air has been removed.  This is especially true if the
system started out dry.  Believe me, I've gone through this.  A spongy
pedal is the classic indication for air in the system.  To completely
expel all the air may require many cycles of bleeding/driving.  The
driving part dislodges trapped air bubbles which should then raise to
the highest point, which should be where the bleeder valve is.  One
suggestion I've heard, but never tried for dislodging trapped air is to
use one of those vibrating metal scribing tools.

Another possible reasons for not being able to bleed a clutch is that
the slave was installed upside down.  On many cars this is very easy to
do.  I did it on the snake when I redid the hydraulics.  I've talked to
a number of people who have also done this.  Embarrassing, but easy to
fix.

In the last issue of the ACOC newsletter there was a letter from a
member with a story very similar to yours.  He had installed a new
clutch slave on his ME3000.  The slave had been shipped from the factory
with the bleeder valve screwed into the inlet because that was the only
way it would fit into the shipping box.  There was apparently no mention
of this in the instructions that came with the new slave.  The member
discovered this after checking another member's car, then calling the
manufacturer to confirm his suspicion.
