ABSTRACT:
An internal combustion engine includes a cylinder block, and a plurality of main bearing caps secured to the cylinder block at a predetermined portion. A flange integral with the cylinder block has first and second end walls extending from the cylinder block and spaced from each other, and a peripheral wall which interconnects the first and second end walls. The first, second and peripheral walls cooperate with the predetermined portion of the cylinder block to define a chamber. The peripheral wall is formed with an opening communicating with the chamber. The opening and the chamber serve as an access to the predetermined portion. The opening is closed by a plug.
