OK, just done this test. Absolutely no pressure build up or surging or fumes or oil in the expansion tank. It looked exactly the same as before I started the engine.
Where to go from here?
I'm concerned that continued use and constant coolant topping up may contaminate the oil and damage the turbo. The oil level isn't rising noticeably on the dip stick.
