Default Sounds to me like you are getting some oily substance micro-dispersed in the coolant while car is

running and then it disappears after the car has been shut down for a while (actually probably floats to the surface). Look inside the expansion tank for some oil floating on top of the coolant - try soaking it up with the corner of a paper towel to see the two phase separation.
