Hi nice people

I had a really small antifreeze drip coming from my engine and decided to
add some bar's leak to see if this would seal it up. The leak seems to have
stopped but when I checked the filling tank, about 3 days after adding
bar's, I find that the antifreeze has about 1 inch of milky white liquid on
top of it. The engine runs fine and the temperature gauge reads normal. I am
wondering if anyone has used bar's leak before and had the same thing
happen. Could this also be a sign of a head gasket leak? I would welcome any
advice on this matter.

Thanks,
