Pls help: RMS vs IMS failure?

[jhandy]

I understand the difference, I just dont know in which direction does the oil flow.

hang with me for a second:

If it works like this: the oil from the motor, goes through the bearing, and then to the rear seal, then to the garage floor... more oil on ther floor would be good in that the old motor oil is not blocked from "passing through" and does not back up inside the bearing.

OR

the oil goes to the real seal area, and then pools, then seeps into the bearing, and into the tube, and back out the tube pass the bearing. In that case the rear seal leak would have not much to do with failure.

OR

Am I wrong in both areas?


Also why does porsche not just recall the cars and fix the issues and thier reputation by doing the retrofit as a recall.
