ABSTRACT:
A decomposable casting core (56a, 56b) is formed in-situ with a sleeve-like liner member (64) and the assembly mounted within the mold cavity (24) of a cylinder block casting mold (22) for lining piston cylinder chambers (62a, 62b) of a cylinder block (26) cast within the mold (22). The liner member (64) is formed with an inner annular recess (80) which receives a corresponding annular projection (76) of the core (56a, 56b) for preventing the liner (64) from sliding axially on the core (56a, 56b) during casting.
