Not sure I can see it in that pic. Looks like the case was re-pocketed, maybe that’s why. If it’s just a small crack in a thick part of the case and it doesn’t go through to cause a leak it will be ok for a while longer. If the crack is into the bearing pocket I would think it might spin the bearing when it gets hot.
