If you have oil in the coolant then a flush would be needed after the head gasket is repaired.

I ACCIDENTLY PUT MOTER OIL IN THE COOLANT. WHAT WILL THIS DO TO MY CAR? iT'S A 96 CHEVY CORISICA.
It will probably make your car overheat but no big deal. Flush it once or better yet twice and then install new 50/50 coolant.

Your hoses will start to swell over time and get soft if you put oil in the coolant
