Those are not good signs. They point to a failed head gasket or internal engine damage causing the same issue, coolant getting into the oil and combustion chamber. Because of those signs you don't really need to do any testing because they provide the answer already.
If it hasn't been going on long you can likely save the engine by replacing the head gasket, having the cylinder head surfaced and doing a few oil changes to flush the coolant out of the oiling system. However you may want to consider the cost of doing the repair against either engine or vehicle replacement depending on the condition of the vehicle. In this vehicle the fist step for this repair is to remove the engine from the vehicle and because of that a used engine might be cheaper overall when you factor in the machine work, parts and lost time to take the engine apart and do the repair. On the other hand you would have the engine out and if the head and block are usable it wouldn't be much more effort to do a rebuild of the engine you have.
