Original engine was replaced at 105,000 kms due to scored cylinder #6. Had done the LN IMSB upgrade (during clutch job) at about 95,000 kms and the original bearing was in perfect shape.
BTW: my engine could have been rebuilt, but I got a smoking deal on a new X51 from Porsche which I couldn't pass up!

Original IMSB replaced at around 115k miles with the LNE replacement. Mechanic states that the original bearing was still in good shape.
Car is a daily driver and has taken part in numerous DE and autocross events. Uses Mobil 1 0W-40 oil.

2004 996 C2 no issues at 75k miles but replaced IMSB with LNE while having the clutch replaced. Original bearing appeared to be fine with no visible signs of wear to bearings or race.

IMS failure at 11910K at the beginning of 2010. PO paid for labor and porsche supplied new crate motor even though car was out of warranty as he had all maintenance performed at a dealer.

We should do a d-chunk failure survey. I bet there are more of those than IMS
