Oil drip, blown all over engine, dip stick shows full. I check frequent. What?

What is your question?

At first was told the crank seal was leaking. Later I found anti-freeze dripping under the car. I do have to add anti-freeze often. Now, maybe the water pump? Mileage is 227,900. I can't afford a new engine(or car). Will repairing afford me more mileage or is engine ready to die? Approx. cost?
