first i would drain it all out and see what it looks like, lets hope its just rust and antifreeze mixing,if it is oil in the water 'mayo' then it may be head gasket,but i would drain, run it drain run etc to make sure it all comes out,just run it on clear water for a few days to see where you are, you can add antifreeze later if its ok,if you take off your header tank you can clean that with oxi.
if its HG it will be expensive to repair, you 'may' get away with leak stopper for a time,what does the oil look like, any steam from the exhaust?
