So is the thought to run a pump inside the IMS shaft using the rotation motion of the shaft and the stationary bearing retaining stud? The oil then exits through an open bearing into the crankcase? I'm not sure what type of pump would lift the oil, but this concept is intriguing. Maybe some type of modified stator vane pump? First pumps air to create a vacuum and lift the oil, and then can handle oil as well? That would eliminate any new moving parts, make the stator and vanes part of a new stud and IMS tube closeout? Neat idea. Lots of technical challenges come to mind. Keep going and have fun!
