This is exactly what I am trying to get to. How many of us have actually followed through as he stated and have experienced a failure?

Or, I would ask, how many of us saw a perfectly intact IMSB when upgrading to aftermarket solutions after such driving/maintenance practices?

This thread would mostly be valuable to either original 996 owners, maybe 2nd hand owners if purchaser was familiar with first owner's driving/maintenance habits, or worst, 3rd owners with this information passed on. Basically enthusiast owned, passed on...

Point is, I am looking for someone to come through and say I tracked my 996 on weekends, or only took it on spirited drives, maintained it...and still the IMSB failed/was intact when upgrading.

Again, this response would not apply to another owner of a 996 who did not know the driving history of their car. This is all I'm very interested in. I know 3 original owners of 996 cars. They drove them 88k miles, 124k miles, and 90k miles all on the original IMSB. They also drove/maintained their cars like I stated above...hence my question.

Oil failure... Then bearing failure, then rod bolt failure.

There is a correlation between post count and likelihood of posting an imsb thread. I think this is much more demonstrable than op's theory.

LOL. Some of you guys really have so much time to come up with these creative answers. Guess life's not been so exciting lately. Thanks though. I like the script writing. Keeps me more in tune with Rennlist. I guess it is actually true what some of society think about P Owners. Glad I'm still not one of them...

Some of theses guys get angry because they know that these engines are ****. Massively flawed on a number of levels. I don't care. If mine goes bang I'll just a chuck a used motor in there and wait till that goes bang and then rinse and repeat.

The car in my avatar is an 01 986S. From what I understand, my 3.2 engine is similar to what is in the early 996 cars. Anyhow, it has 90k miles, and probably the last 15k of those miles have been on track. The engine runs strong. When I had to rebuild the tranny a few thousand miles ago, I did the ceramic bearing upgrade. The mechanic told me the original steel bearings were pristine. N=1 anecdotes aren't worth much but thought I'd pass along my history FWIW.

No we are angry because so many new members post the same old tripe without bothering to read (or comprehend) everything that is already out there. Every newbie has a grand new idea about the cause or correlation, but if they bothered to read they'd know it's all been discussed before.

And now we see this twit is stirring the pot and doesn't even have a 996. I'm shocked about this revelation. Shocked I tell you!

The IMSBS is far over blown to the number of actual failures. It's a risk, but there are plenty of other risks in the M96 just like there are risks in any motor you buy for any car.

I have no more fear of our motor dying than I do of getting hit by lightning. I'll do things as appropriate to help it live longer, but I'm not going to go out of my way to throw money at problems that are a relatively low risk. In the meantime we have enjoyed it for 15 years and will continue to do so.

If the IMS thing keeps you up at night, just don't buy the car. It's really that simple. Like any product, if there is a feature or design issue you simply can't live with, don't buy it. Plus I just wanted to post my new avatar.

While I may be a douche - I assume that's what you're suggesting society thinks about Porsche drivers - my reply wasn't really just an attempt to be clever.

It seems like every potential 996 owner (or, worse, the ones who buy on impulse and THEN read about the IMS bearing online) on Rennlist starts a "I read all of the IMSB threads, but I'm going to phrase this one just slightly differently so I feel justified in posting it. Please agree with the theory I'm posing so I can feel better about my 996 purchase" thread.

Hell, I was tempted to post one when I bought my 996, even though I'd already been driving an M96-powered car for 2 years. The temptation is strong.

To save time, I have added a list of known-to-be-true facts about the 996 and the IMS bearing:
* If you make only right turns, the IMS bearing will last forever.
* If you examine your oil filter weekly with a scanning electron microscope, the IMS bearing will last forever.
* If you shift at exactly 5,996 RPM, the resonant frequency the IMS was tuned to by those crafty Germans, the IMS bearing will last forever.
* If you drive your car in the rain, the IMS bearing will fail almost immediately. NO LIE. Please do not test this theory out.

You forgot #5:

* Conversely if you drive it in the snow, the IMS will last forever.

Well, EVERYONE knows that, but since you'll be tearing the motor apart annually to address bore scoring, I figured I'd leave it off the list.

#6. As soon as you buy a "new to me" 996, you must spend at least $5,000 on "preventative" maintenance, which includes replacing many, many parts that are currently working just fine and have been performing properly for 11 to 16 years, because, you know, at some point, they might fail. Failing to replace any and all of these parts will cause immediate IMSB failure.

And Schnell, you "may" be a douche? Don't sell yourself short, you're a tremendous douche. EVERYONE knows that.

Oh, I forgot to add a well deserved photo:

Thanks - I need to remember to be more self-confident. I appreciate the affirmation.
