1998 Dodge Intrepid?

Engine Mechanical problem
1998 Dodge Intrepid 6 cyl Front Wheel Drive Automatic

The car runs perfect, just like a new motor. But its blowing moisture out the tail pipe and if I rev the motor it spits water about 6' out and forms a small puddle behind the car. There's no moisture in the oil at all the heater turns cool unless I rev te motor up but as I said the engine runs perfect.
