Who do you recommend in the NW Burbs? I missed the opportunity to talk to you at the recent Porsche club gathering a few weeks ago.
Question:
IMS - Are the issues for all M96 or just early years 99~?? that are subject to failure?
Thx,

Search for Jake Raby's post on M96 failure modes. Good reading, if not a little anxiety inducing.

Currently, the only shop in the Chicagoland area that has done it is Joe Rizza Porsche, and they are very experienced with doing it. Another individual whom I met at the winter Tech session had Rizza do the work and they were very pleased with the price and level of service he received.
Chris Schuh in Wisconsin also did one recently during an engine swap for our local region autocross chair who lost an engine to oil starvation at R.A.

I was at one of Jake Raby's sites - he has some great M96 engine articles there, like this one on replacing the IMS bearing: http://www.flat6innovations.com/savi...e-ims-retrofit
Just thought people would find it interesting.
Van, what did you end up doing ?
and are you going to Lime Rock this weekend ?

Lets just say that the majority of the IMSR procedures I have carried out have given us some of the best testimonials in the history of my company. Its fairly difficult (generally) to exceed the expectations of a discerning owner when applying a preventive procedure thats not cheap.
These owners have driven or shipped their car from various parts of the country to have work done that doesn't give them any added performance... They never feel or see the difference the IMSR affords their engine.
Amazingly, they are among the happiest group of people I have ever worked with after the fact.

I shipped my car from Rhode Island to GA, and it arrived back fine and I am not sure if the IMS would ever be an issue for my car, but at at least I took some action that should have positive results - both from a car standpoint and my paranoia level
(and also the other stuff like clutch kit, water pump, and other stuff that needed some attention like a sticky lifter and the other common while you are in there stuff RMS etc.).

Ceramic bearings are that expensive. Porsches are very high profit margin cars. Porsche engineers neglected to provide adequate lubrication to the bearing and assumed that sealing the bearing would fix it. they were wrong. Porsche has designed out the IMS. IMO, that was the wrong direction.

Burning Brakes
You need to read up on the subject. There is a history and reason for Porsches use of the sealed bearing there. There is no cooling via fresh supplied lubricant, so needle bearings would not last 100 miles. Plus there is rather large amount of needed axial play and loading, not suitable at all for needled bearings. The load, temperature, and lack of lubricant flow make the ceramic bearing the best choice.

Temperature- use ceramic not high carbon steel
Axial load- ball bearings can not support axial load, only thrust or tapered-roller bearings can be used.
Axial misalignment- dual row ball bearings? eh? Tapered-roller bearings can handle some misalignment.
Porsche's solution was to eliminate the IMS altogether instead of providing sufficient lubrication.

Only problem here is that you have no data on the quality,performance, or longevity for this kit, the LN unit has over 4,000 units installed in the field. I'm sure Casper knows their bearings, but I would be remiss if I did not note that LN and Jake Raby tested the Hell out of the LN unit before they made it available; I have seen no data on what level of testing this other supplier has done....
