Abstract
An apparatus for cleaning a passage in an engine block, such as the oil galley and oil galley legs, in which the passage includes an inlet and an outlet end. The apparatus includes a fixture having an interior passageway with an opening. The fixture is dimensioned to abut against the engine block so that the opening in the fixture registers with the engine block passage outlet. An air induction source is then fluidly connected to the fixture passageway so that, upon actuation of the air induction source, the air induction source inducts air through the engine block passage, through the fixture opening, and through the fixture passageway. A feeder containing abrasive shot is then coupled to the engine block passage inlet so that, upon actuation of the air induction source, the abrasive shot is inducted through the engine block passage and into the fixture passageway.
