IMS Failure is not a Myth.

LN hasn't sold anywhere close to 10,000 replacement bearings. Sure, maybe some people part out the car rather than repair it but then you also have to take into account that some large percentage of LN bearing sales go to cars that have never had a bearing failure in the first place (preventative replacement).

With more than 10,000 cars suffering failed engines, the aftermarket/eBay would also be flooded with failed engine Boxsters and we just don't see that.

The only conclusion is that the engine failure rate is much less then 5% (or failed Boxsters are with all of the socks that disappear from the dryer).

As the owner of an independent Porsche shop, I have to respectfully disagree.

This single VIN has experienced TWO failures in 118k miles.

All I can report is what I see. What I see is between 10 and 20 percent.
