I'm betting that you have a leaking intake manifold gasket. That engine is notorious for that. I would remove all the spark plugs and then do a cooling system pressure test leaving pressure on it for a good bit of time and then spin the engine without plugs watching for one of the cylinder to spit out coolant.
