Thanks Jerry, you're entirely right... I didn't even think about how the coolant passages do not go left to right, other than in the intake. That's what I call ADDED VALUE!
That should narrow it down even further. Not seeing a FE coolant flow diagram I would assume the the right side water pump block entrance just feeds the right side of the block and visa versa for the left side.
As I'd said, I never had the froth until I had the coolant leak. It never produced the froth before for two years, with the other intake and the exact same ventilation system (2 breathers and a PCV) and the same finned valve covers.
