If there was a water leak into the engine oil it would look like whipped brown milk.
When the engine is up to operating temp any misc. moisture is evaporated out of the oil, along with a bit of oil vapor. Perfectly normal unless the oil vapor is coating the bottom of the hood or front of the engine.
And also why it's a good idea to drive a car until everything is up to full operating temp, not just start it every now and then or only drive it short distances, esp. over the winter.
