Isn’t there a tester that checks for
the amount of CO2 in the coolant? This would be able to spot small leaks,
before they become catastrophic problems.

leak
I really really think that a cooling
system that consumes coolant is leaking it somewhere, either venting water
vapor to the atmosphere or leaking. I don't follow
how your coolant level can be going down and yet you
still have residual pressure, shouldn't the pressure drop to
zero as the coolant is consumed over time?
A rotary is unique in that depending on
where an o-ring failure occurs relative to the intake port you can
end up with a little problem or a big problem. As you rotate
past the intake port the compression chamber pressure goes from 0 to over
a hundred PSI, once the plug fires the pressure skyrockets due
to combustion.
If I were getting combustion pressure in my cooling system I think I
would be boiling off my coolant PDQ. But I find that it only drops very
slowly, about like in my car.
