The best insurance policy to eliminate porosity and pin hole leaks in your castings is Interna-seal. Add this pack to your cooling system,where it remains suspended and seeks air. It will not clog your radiator or core support,and is totally harmless to the rest of the vehicle. This is the best internal sealant we've found in our 40 years of casting repair,and we've tried them all!
