It actually seems like it would have been a good idea to have the tube filled and seal only on outside of bearing. If one takes the LN approach Porsche would have been better off not putting the seal on the outside after this mistake...at least it would have been exposed to some oil.

Hi Whip, Yes seal was inadvertently put inside instead of outside. No, just the first order of double row of bearings from NSK. Which was how many bearings? Enough to build engines through 99? I don't know,......, but I do know Porsche ordered them missing one seal and no lube. I was working on getting the info for the ordering of the second seal when they found out it was about Porsche, then NSK shut me down. Right now I am in communicating with a company about gear oils that was used in 96.
Like I said, I think there was a communication break down inside the company between Depts. I have seen it several times before in business as they would rather hide the mistake than expose it as their fault. This is just my theory and I am sticking to it, unless info comes to light that would change my direction here.
I am not sure if the steel balls in the original bearing would of lasted with the seal off in a dirty enviornment.
Everyone keeps saying engine oil entered the tube through bad seals but the bearing would have to be submerged in oil to have that much oil stay in the tube. Since the bearing isn't submerged, oil would drain out of the seals when it went bad.
