Claim 13:
14. A turbine engine comprising:
a casting defining a wet cavity;
a housing including an annular wall extending about an axis and axially between a first housing end away from the casting and a second housing end proximate to the casting, the annular wall including:
a plurality of holes spaced circumferentially from one another and spaced axially from the first housing end, the plurality of holes extending through the annular wall toward the axis; and
an interior housing surface extending about the axis and defining interior openings of the plurality of holes, the interior housing surface having a cylindrical portion circumscribing a bearing cavity in fluid communication with the wet cavity, the cylindrical portion extending axially from a first location proximate to the first housing end to at least a second location between the first location and the interior openings, the plurality of holes in fluid communication with the wet cavity via the bearing cavity;

a bearing including an outer race extending about the axis and axially between a first outer-race end and a second outer-race end, the outer race received by the housing inside the bearing cavity such that the first outer-race end is located proximate to the first housing end and the second outer-race end is located proximate to the interior openings.
