I've taken that all apart and checked it out and I'm fairly confident that
the bleeder screw is not leaking. I put some teflon tape around it too. I'm
going to look at it again this long weekend.  I could be wrong.  Your
description of where the coolant collects makes me suspicious.  Can I get
another bleeder screw by itself from the dealer?

HOW DO YOU DO THAT! Wow, that WOULD make it easier, but I couldn't see an 
easy way to get it out.

That's an odd way to do it. I clamped off the hoses and pulled the whole 
thing out.  However, your way would sure show me if there was a leak 
while it was running.  It's a small leak however and might not be noticed 
just in normal running.  It would also save me the hassle of bleeding the 
system each time.

I'm going to tear it apart again and I may contact you on that very soon.
Thanks a million for your tips!
