my timing chain cover is leaking coolant

I have a leaking timing chain cover which is dripping anti-freeze I was told the cover is warped. The cost of repair is more than car is worth. Can I continue to drive the car and add anti-freeze or will there be other consequences? It looks like the dripping is behind where the water pump installs it is a very slight leak. I'm not sure but I don't think they make an after market cover. I viewed the procedure and it does seem like a job of proportion. Car has many new parts but it is one thing after another and appears the options are very limited at this point for such a repair other than putting big bucks into it and not knowing what gasket will need repair next.
