if ur motor oil level is low, which it most likely is, then u prob have a puncture n ur engine oil cooler. I'm no automotive wizard, but we've had this happen in a combine and a tractor (altho both had diesel engines of course). I believe we used kerosene to try to flush as much oil out of the radiator as we could after fixing the leak. This problem is a better one to have than the opposite (coolant n the engine oil).

If you check the oil and it's white, foamy or just looks like crap, you have a bad head gasket. It is very rare, but could have a crack in a water jacket and it's getting into your water that way. But I'd go with head gasket.
