Inspection was done last Friday. The mechanic took a look and also pointed to the waterpump as likely suspect. Looked up the price and we decided it is worth a further look.
Today I removed the access cover so I could take a front look. All dry above the waterpump, little coolant drop on the pulley. That can't really come from anywhere else than the pump itself. So I ordered a new pump (Magenetti Marelli, should be good enough) with new (slightly longer) belt and a brake light switch (reason it failed inspection initially).
The only plastic impeller pumps are very expensive (more than 5 times the price), so I did go for the metal one. I understand the whole reasoning for plastic, but am sure it will live the few thousand miles I will put on this engine. Funny part is I actually did break an early model plastic impeller pump on the BMW I had at the time. The impeller let go of the shaft, so was no longer spinning. Things overheat quickly at 150 MPH... Still the engine survived for the next 60k till I sold it...
