No leaks visible. No sign of funky exhaust or funny look in oil. Does not overheat. Heat
works fine. Just losing coolant. Any ideas appreciated.

Possibly a small crack in the bottom of the radiator.

If so why would it only leak when car is running and not when its just sitting?

I had one that drove me crazy. He could drive it all day and not leak and let it sit overnight and there would be 2-3 drops laying in the bottom of the fan shroud. Took me 3 times to find it with a pressure tester.
