When you get coolant in the engine oil, you greatly decrease the oil's lubrication properties, then you get rod knock/spinning bearings (very expensive to fix).
Don't drive it or let that crap run through your engine oil passages if it is indeed oil and coolant mixing.
Is the oil foamy at all?
Do you have oil residue in your coolant overflow tank?
Performing a cooling system pressure test may or may not indicate a leak since sometimes leaks are intermittent. I would try it though anyways.
There are other tests, but they may be over your head (no offense--I was a new to engines to once).
Do you know of any mechanics that would let you borrow their tools?
