Blown head gasket or intake manifold gasket. Pressure test the cooling system with the engine cold. The cooling system should hold pressure for at least 10 minutes. Also, with the system under pressure start the engine. If the needle on the pressure tester gauge bounces, the head gasket is blown. Hope that helps! Jim
