A little oil in the cooling system won't really hurt anything.
well post #2 already said that so didn't need to repeat. i beg to differ.. oil in the cooling system makes a big time mess and you need to citrus/chem flush to get it out. guess it would depend on how much oil...
suffice to say not a good idea to run the engine like that.
