All IMS Engines will fail?

I don't believe the IMS hype. EVERY car has something that they're known for that could have been better thought out from the factory.
When I did my clutch at 100k miles I swapped out my bearing for the LNE version since I was in there anyway and my original bearing was good as new when it was opened up and inspected.

That's just crazy talk as you need to replace your IMSB before a 300 mile road trip just to be safe!! Well according to Krazy K anyway - I did 500 kms this weekend just for fun on an original single row bearing -- oh the horror!!

Yep - I did about a 3400 mile round trip in the C2 about 5 years ago, it was a blast and I still have many pleasant memories about the drive. Took the C4S on about an 1100 mile round trip shortly after I got it, good trip but not as long as with the C2 and not as exciting. 14,000 miles after the C4S trip and I've got a new Porsche motor - breaking it in and trying to convince the wife to join me for a coast to coast jaunt by car later this summer.

My latest failure email:
"I have had a engine failure from an IMS failure in my 2002 Porsche. I would like to schedule a time to speak with you regarding my problem. The car has 11,500 miles on it and looks like it just came out of the showroom. I bought the car, drove for 1500 Miles in 30 days and lost the engine. Please identify a time for me to call to discuss.
Thank you,
George"
As far as what Joel stated, well the way people react to things these days is why you'll never see me writing articles. Heck, seeing these types of comments makes me wonder why I should even finish my book.

Jake, what would you say the ratio is of cars that have come into your shop with failed bearings over the years that have less than, say, 40k miles to those that are "high" mileage cars with 80k+ miles on them?

This is another of those questions that will just lead to other comments and I'd end up much like Joel Reiser has in this thread.
There was a time when you could say the sky was blue and people didn't hate you for it; the modern human hates to be told that the sky is anything other than a huge rainbow with glitter on top of it.
I have avoided the IMS failure topic completely in my book, just because of this. I go over how to perform an IMSB retrofit using the conventional components and how to install the IMS Solution, but I don't even state why the bearing should be replaced.

I see no reason to have any fight about it. it is very simple engineering issue - a life expectation of a bearing partially submerged into hot oil. depending of level of vibrations and imperfections of entire IMS assembly it is quite obvious that time to failure is difficult to predict but it is obvious that a probability of a failure for a bearing in such conditions is hundreds times higher than for a bearing that is working in normal expected conditions. what people may or may not think about it - who cares.
still if there is such a statistic it would be interesting to hear about it, in my case I would really want to know what happens to newest generation of 06-08 cars now with newer bearing, is a failure rate there really goes along with mileage or repeats pattern of early 996 cars?

The IMS bearing is now so cheap and easy to replace, there is NO reason not to replace it as a regular or preventative maintenance item. In other words, I would trust what Jake says over the BS rhetoric.
