Your presumption has been proven wrong. We tracked our database of dozens retrofitted cars VIN's against what bearing we found in the cars when retrofitting them against the lawsuit's "exclusions" and found no relationship to the style of bearing that was in the car and if it was excluded or not. There is no discernable or statistically sound relationship between the two. To date, no one has been able to demonstrate why the lawsuit excluded certain cars.

As we do this for a living, I am well aware of what is found in the oil sumps of these engines. The big difference is the type of metal found; all engines produce very fine ferrous metal grit, usually so fine that it can actually pass through the oil filters. When an IMS bearing begins to shed metal, however, the size of the ferrous grit suddenly becomes much larger and profound in volume.
