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

I would have to contact my Crystal ball to be able to answer that question. Removing the intake and looking is the only way you're going to find out the answer to that question. You will see the damaged gasket. If the coolant is going directly to the crankcase, odds are pretty good that it's an intake gasket causing it.
