Thanks for all the help!

Investigation of the expansion tank revealed telltale deposits around the coolant
level sensor. Since when I had the system flushed the shop put in a new cap because
it was whistling, my guess is that this boosted the pressure just enough to get the
marginal coolant sensor level O-ring to start leaking as well.

Trip to the dealer for a new coolant level sensor and $8 later - all seems well
again.
