If you have a Ls2 saturn 3.0L its not a oring its usually a bad oil cooler that starts leaking oil into the coolant it's located under the intake manifold under the oil cooler plate.You would have to remove the oil cooler and put it in water and pressurize it with air and see if there are bubbles.I have seen a lot of them leak and do what your talking about.
