Abstract: This invention relates generally to a method for repairing a casting (10), and more specifically to a method of repairing a casting (10) by pouring melted filler material into a damaged portion of the original casting. Damaged cast metal components (10), such as a cylinder head of an internal combustion engine are repaired by preheating the component (10) to a first preheat temperature. The damaged area of the casting (10) is then heated to a higher temperature using a torch and melted filler material is poured into the casting (10). The torch is used to maintain the temperature of the melted material for thirty seconds to two minutes. The temperature of the filler material is then cooled using compressed air.

Abstract: A method for manufacturing an engine block (10) includes removing material from the top deck (18) of the engine block (10) surrounding a first opening to create a first recessed area (22), placing a first seal (90) within the first recessed area (22), positioning a first insert (50) within the first recessed area (22) and against the first seal (90). The method may also include removing material from the top deck (18) of the engine block (10) surrounding a second opening to create a second recessed area (70) that at least partially overlaps the first recessed area (22), placing a second seal (95) in the second recessed area (70) and positioning a second insert (78) within the second recessed area (70) and against the second seal (95).
