If it is leaking into the oil it will not be running "good" for long. Find where it is coming from(oil cooler, head gasket etc.) and fix it. Driving it this way will kill that engine.

Couple places the oil will mix with antifreeze..... Oil cooler, front engine cover plate or the valley pan.

Done any work lately, does the rad have oil on the surface of the A/F.
