I have spoken to the service person at the dealership and she of course remembers the whole deal and is going to type up a letter to enclose with the paperwork clarifying the cause of the failure. Hopefully it will be explicit enough to satisfy the lawyers. I can't help but feel that there may be a larger IMSB problem than their percentages show due to many being replaced without it being attributed to the IMSB. When the dealer changed it we discussed that that was the cause of the failure, but they did not show me anything and I do not know what disassembly or diagnosis they did and at the time I did not know the relavent questions to ask and had given up on getting any relief from Porsche. If I had been privy to this forum prior to the failure I would have been much more knowledgable although since the law suit had not been filed at that time maybe no better off. I am certainly getting more more skeptical and careful and less trusting.
If anyone is tempted to use German Motor Works in Asheville, nc I absolutely advise against it. He either charged me 3 hours labor for the 5 minutes it took to pull the filter and find metal in it and did nothing else or he did 3 hours of comprehensive diagnosis and failed to record it and is so pissed off about not getting an overpriced engine swap that he is intentionally screwing me.
The engine swap is not something I would have tackled myself, but the whole experience has made me even more determined to do as much of my own maintenance as possible and to learn as much about my cars as I can.
