Do you have a PCV valve properly installed in one valve cover? If not, you NEED one. It's most likely a small amount of blow by which is normal. (if there is NO pcv valve)

It's also possible it's steam!! (ouch! not good)

Pull the drain plug on the pan a little and see if any water or antifreeze drips out. If it does, you got problems.
