White smoke is generally burning water. Usually from a blown head gasket. To verify that you would want to do a pressure test and a combustion gas test on the cooling system. If it fails both you have either a bad head gasket or cracked head or block. Then you have the option of repairing it or replacing the engine, which is what I would suggest because of the high mileage on the engine.
