Abstract
A tool and a method of forming an engine using the tool are provided. The tool includes an insert and at least one die. The insert is formed by forming an interbore passage between first and second siamesed cylinder liners, casting a lost core, and then casting a metal shell. The insert is positioned into a die of the tool and the engine block is cast. The lost core material may then be removed to provide the cooling jacket. The engine includes a cylinder block with a cooling jacket circumferentially surrounding first and second siamesed cylinder liners intersecting a closed deck face. The cooling jacket has first and second widths in first and second axial sections, respectively. An interbore region of the first and second cylinder liners defines first and second interbore cooling passages spaced apart from the deck face and parallel to one another.
