Boy am I confused about local boiling. Thought that yes maybe cool momentarily while it initiates, but if a film stays in place that the heat transfer goes to zip and damage to parts occur. 
 
Me too.  I almost wonder if we aren't getting worse than the other list sometimes. 
 
 I like your idea about no pressure and measuring coolant level for leaks. 
 
Thanks.  After my oil cooler ordeal, I did that as a way to feel better about the remaining evap cores that are being used for coolant.  I know this is not the same as using them for oil, but I'm happy that I will know if there's a leak, before it becomes a problem.  
 
What is the difference between R and +. 
 
 
The -R is lower viscosity, which I figured should be better for us.  Even with this lower viscosity, it causes some problems with the EWP in cooler temps.  This fact might cause me to use a mechanical pump, with EWP backup on the Kolb, like I do on the RV-3.
