Question about 1997 Pontiac Grand Prix
Sorry Dusty, it's bad. I think you'll find that the head gasket(s) has failed, which is bad enough, but with oil in the coolant it means that there is also coolant in the oil. Modern antifreeze destroys the bearings in the motor in a short time. The motor is likely toast.
You can try some head gasket sealer, there's a lot of it marketed, but once a gasket gets as bad as yours is it's very unlikely that it will work.
