Thanks Jay. Maybe my thermostat was occasionally opening (hence the spray), whereas yours didn't, and that's why you never saw the spray.

Thinking about it now, when I brought the engine up to 1500 RPM, that would obviously increase the engine operating temp. From there, suddenly bringing it down to 700 and reducing the pump speed and flow rate, perhaps that would cause just enough of an increase in coolant temp to pop the thermostat. It was probably right on the edge.
