Just curious, since the Turbo oil gallery is pressure-fed with oil, why would it need a gravity-induced oil return? Would the oil not just pressure-feed back to the sump with the residual pressure when running and the oil return's routing prevent the sump oil from running back?

  Any back pressure at all will cause oil to go passed the carbon seals.
