IMS shaft filled with engine oil

I removed the IMS shaft from my 2006 Cayman S M97 3.4L and set it aside horizontally for about six months. I was rebuilding the engine due to a connecting rod. I had never touched this IMS bearing during the 115,000 miles. When I removed the ball bearing (6305) from the shaft, it surprised me that there was about a half a pint of engine oil trapped in the shaft. I took apart the 6305 ball bearing and found no grease. So even with both of the dust shields installed on the bearing, oil was getting into the shaft and washing the grease out of the bearing. The bearing was containing the oil while horizontal, I assume that during track days or normal use that oil traveled through the bearing, into the shaft. Has anyone else noticed this, and did you do anything else based on it? Upon rebuilding I installed a Brock’s Performance/Worldwide Bearings CB-6305-2RS. It has ceramic coated ball bearings, and the body is made by NSK for motorcycle wheel bearings. I kept a little bit of the engine oil (tablespoon?) in the tube before installing the bearing.

Totally normal to see oil inside the IMS tube on a used intermediate shaft. The grease seal get hard after years of repeated excursions to 250F and fails, allowing the engine oil to wash out the grease in the bearing. Since the shaft is submerged in oil, it ends up filling up with oil.

When the oil level is at full with the engine off, where is the oil level relative to the IMS shaft?

There are people who say "oil washes the grease out and then it runs dry". I ask "did the oil go in there with the intent to wash out the grease and then stop going in?" Not likely. I also believe in leaving the seals intact to retain a little oil if the sump level is not checked regularly. I suspect the IMSB is submerged when the level is correct and the natural thermodynamics of expansion and retraction push oil in and out regardless of the seals. The Porsche Factory stays totally out of this discussion and keeps their discoveries to almost everything private. It would be interesting to construct a test assembly to see if there's pressure or flow thru this thing just to clear the confusion. I'm curious about the ceramic bearing construction. Did it have 7 balls or 8? The factory 6305 is a heavy duty bearing that has 8 compared to the standard industrial brg that has 7. Did you have the crank chromed up and reground? I had to do that and 50,000 miles later I have a small tick that might be a bearing getting loose. Thanks for any reply.
