Thanks Finn and Ed,

So thaaats what those little washer were for!  Luckily, I kept them but
you are right that they are probably the cause of the leak because I
didn't have a gasket (notice that they are about as thick as a gasket).
I was just using a layer of permatex aviation gasket maker - the brown
stuff that is pretty thin.  

Although I only have about 1/4 inch clearance between the firewall and
the water pump pulley, Finn was right.  I was able to coax some regular
gasket maker into the space and make a very sloppy but effective seal.
While at it I was able to seal my pin-hole leaks with JB Weld.  The oil
leaks fixed easily (uh, it really helped to tighten the fittings with a
wrench).

I also owe an apology to Atkins Rotary who did install my CAS correctly.
The errors are all mine.  Turns out that somewhere along the line I lost
track of which signal went to which coil to which spark plug.  Out of
desperation I swapped the leads between the front and rear rotors and
WOW!  Sure does run MUCH better with the proper spark plug wires going
to the proper rotors.  It is really really amazing that I was able to
run the thing at all! (not to mention the fact that I didn't install the
engine backward or something the that)

Today I get to slide in the nav/com and go taxi around! It sure is going
to be tough to go back the sanding the cowl(and worse yet, the job). :-)
