It sounds like you have a head gasket leak. Otherwise known as a blown head gasket.

If any coolant is getting into the cylinder it will make things worse to keep running it. Diesels are very sensitive to fluid in the combustion chamber.
You might get away with just the head gasket if you get on it now. Waiting will only cause more damage.
