vacuum or air intake hose leaking or disconnected or loose...? good luck:)
Check your crankcase ventilation, the hose or pcv may be blocked or disconnected.
Look for an intake manifold leaking at a cracked or disconnected hose or one of the gaskets to the cylinder head or throttle body.
Is the water still leaking? If so was the original line disconnected?
Either the heater core is leaking or you have a leak at the windshield or the cowl. If the fluid tastes sweet it is coolant and your heater core is leaking.
Intake gasket leaking on the inside of engine.
