ABSTRACT:
A plurality of inter-connected cores includes barrel cores (18). Bore liners (10) surround the barrel cores (18) and are fixed in relation thereto. A cylinder block mold core package (22) is assembled from the cores (14, 24, 26, 28). The liners (10) are heated while they are within the cylinder block mold core package (22) by induction heating. To prevent migration, a mechanical interlock is provided between each liner (10) and its associated barrel core (18).
