Ok, after more research and finally being able to have a disassembled engine that didn't suffer a IMS failure, a few things stand out.
1. The IM shaft was approx. 1/3 filled with oil, not motor oil but it appears to be syn. gear oil by feel. I won't know for sure until a sample is tested.
2. The bearing has BOTH seals on it, I have confirmed earlier with NSK that the bearing was shipped with only ONE seal and no lube. I have written proof of this thru Emails with Eng.'s from NSK.
3. After a quick inspection, the inside of the bearing is like new, smooth rolling, but very little lube (oil) inside, no grease anywhere, as I am pretty sure porsche did not use grease, as no bearing yet has been found with grease.
4. Which leads me to this new theory.... Porsche filled the IMS with an oil, which was to lube and cool the bearing, but, for some reason Porsche filled the bearing with oil and put the other seal on the side missing one and installed the bearing.
5. So... did the original design of the IMS require the inside seal to be removed from the bearing and have the IM shaft 1/3 full of oil to lube and cool the bearing while having it sealed from the engine oil?
6. To me, it appears Porsche had a break down between Designing and Production of the engine. Somewhere something was changed to the bearing.
7. After handling a perfect IMS, I have no doubt that the oil in the IMS design with the inside seal removed, would be trouble free if installed correctly. But who am I to say?
8. Unless my microscope finds damage or I come across more info contradicting this theory, this is how I will intall THIS bearing or mine if it is in the same condition into my '98. (no seal on the inside and IMS 1/3 full of oil.)
