- setting said hollow cylindrical cylinder liner block into a metal mold for forming the cylinder block body;
- fitting an outer peripheral surface of said cylinder liner block into a hollow cylindrical jacket projection formed in said metal mold so as to mate a free end of said jacket pin to a sealing surface of the seal flange; and
- pouring a molten metal under a pressure into a cavity defined by said metal mold and said cylinder liner block, thereby anchoring the cylinder liner block into the cylinder block body in a cast-in manner so as to form the cylinder liner block.
