I would venture a bet, that you have a Lower Intake Manifold Gasket that is blown. And the gasket is causing the coolant to enter the combustion area, and be blown out the exhaust. Come over and join www.w-body.com/forum and I am sure one of the members there can help you further in determining the leak.

Yes there should be a overflow vent in the overflow reservoir. Think about it this why, if it was not there and pointing downward. If during a overheat period the lid were to pop off. The result would be a hot water volcano. Trust me you don't want that. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For more information.
