The leak was at the top seam of radiator. The fan blows it toward the intake thus getting mixed into air intake. That is my guess.

I changed gas to Union 76, Mobile, and Valero from Chevron. I used Chevron exclusively and see if there are any changes with sodium. I am due for an oil change once rain stop here in NorCal.
