Hi there. Different expert here.
The only thing that would explain the cooling system losing 1/2 gl per day and an engine misfire would be a crack in the combustion chamber that only manifests itself once the engine warms up.
Were this my car, I would try a chemical sealer like Blue Devil (click here to view - just make sure the instructions are followed exactly as shown on the container).
