Default Oil and Coolant?

Has anyone encountered the problem of loss of coolant into the oil?

I have done the replacement of the "leaky" seal beneath the impeller.

I've noticed what I believe to be a slight increase in the oil level that
shows on my dipstick, however...when smelling the oil, it has no odor
of anti-freeze to it.

if you are getting a mix of water and oil the oil will be milky looking. if you not sure if you have a leak you can do a pressure check on the cooling system to find out.
