Abstract: A method for manufacturing an engine block includes removing material from the top deck of the engine block surrounding a first opening to create a first recessed area, placing a first seal within the first recessed area, positioning a first insert within the first recessed area and against the first seal. The method may also include removing material from the top deck of the engine block surrounding a second opening to create a second recessed area that at least partially overlaps the first recessed area, placing a second seal in the second recessed area and positioning a second insert within the second recessed area and against the second seal.

Abstract: A self-centering seal for a counterbore with an inner passageway and a counterbore diameter defining a recessed area is described. The self-centering seal includes an annular shape including an aperture defined by an inner diameter matched to the diameter of the inner passageway, a circular outer edge having an outer diameter less than the counterbore diameter, a sealing surface at least partially disposed between the inner diameter and the circular outer edge, and a plurality of centering tabs projecting form the outer edge. The self-centering seal may, for example, be used in engine manufacture in conjunction with counterbores and inserts around fluid passages.
