The Quad 4 and newer Twin Cam engines are known for blown head gaskets and head issues. First lets make sure it's only leaking to outside the motor and not inside. Check your oil. If the level has gone up or there is a milky residue you have water in your oil and you should not run the motor. If the oil is good the issue is smaller. Is the car blowing white smoke out of the exhaust. Does the coolant system pressure up and blow out of the rad cap when running. If your car has none of the above symptoms it is most likely the head gasket (which is not fun). Can you try to locate the leak exactly and post a picture.
