How much fluid is it pushing back into the expansion tank?

The expansion tank would always see some fluid pushed back into it at expansion, it's the reason there is a tank in the first place, and why it needs to be filled between the min and max marks when the engine is cool. Is yours overflowing or something?

Overflowing could mean a bad head gasket or block, but you block tested it already, right?
