Abstract
A restoration process for restoring surface porosity defects in engine blocks cast using a high pressure die cast method. The areas of an engine block having surface porosity defects are identified and the areas not containing surface porosity defects are masked using an adhesive, reusable, rubberized mask. The masked surface is subsequently cleaned and a metal spray is applied to the surface porosity defects. The mask is removed and the restored surface porosity defects are hand finished to create an engine block having less than 0.05% surface porosity.
