A support housing is disclosed for use with a turbocharger. The support housing may have an end wall, a semi-cylindrical protrusion extending from the end wall in a first direction, and a plurality of side walls extending from the end wall in a second direction. The plurality of side walls together with the end wall may form a generally hollow enclosure. The support housing may also include a mounting flange disposed at distal edges of the plurality of side walls, and a center opening disposed in the end wall. The support housing may further include a collection cavity formed at a gravitationally lowest corner of the end wall below the center opening and substantially isolated from the enclosure formed by the plurality of side walls and the end wall, and a gutter passage formed in the end wall and extending from the center opening to the collection cavity.
