Bill,
 
This is a good point and something I have been thinking about.  T= he added NPG was 100% PG but there was obviously a little bit of aquious PG= left in the system.  I tried to burn it off during my hour long groun= d run, but the temp never got very high (toped out at about 180).  Tha= t little bit of water may have boiled over and forced out the evans...
 
Someone else brought up the 7 psi cap with altitude.  That is als= o a possibility - actually a combination of both.
