Overheated on track - now what?

[RETed]

Sorry to hear it's not going too well...

Have you tried to smell the coolant (bubbling)?
If it's combustion gases getting into the cooling system, the smell will give it away.
Normal coolant smell is a lot diffferent from combustion gases in the coolant.

There is a chance that you have a very tiny break in the water jacket o-ring on the combustion / exhaust cycle of the rotor housing.
The combustion pressures can hit around 1,000psi with the exhaust cycle pressures several times higher than the typical 15psi, and this would explain what you're experiencing.
