I wouldn't go any near a glass or media blaster of any kind as the abrasive dust can get into the smallest openings/areas. Had a friend do his oil pan that was supposed to be sealed off. Even said he flushed it several times. Ate the bearings within 5 minutes of start up frown


If it had any baffles, then yes. Same as with most valve covers. But a plain pan wouldn't be a problem.
