ABSTRACT:
A sealed machined member comprises a casted block member having an outer surface including a machined portion and a scalloped portion which adjoins the machined portion. The scalloped portion is cast into the outer surface when the block member is casted. A wet passage is formed in the block member for containing fluid having a pressure which is greater than the pressure adjacent to the outer surface. The wet passage has a longitudinal axis which defines a passage plane. The passage plane extends between the longitudinal axis of the wet passage and the part of the outer surface nearest to the wet passage. The scalloped portion is oriented so that its longitudinal axis lies in the passage plane. The scalloped portion is recessed from the outer surface so that the scalloped portion is not machined when the outer surface is machined.
