Diagnosing a 2000 3500 Chevy Truck and it gives signs of blown head gasket. White smoke, rough start, chocolate oil, however, when I drain oil and fill radiator, the water flows straight through and out the oil pan. I'm wondering if this is definately the intake manifold gasket(5 hours) or head gasket (13 hours)or both?
thanks for your professional experienced opinion
