its hilarious when 09+ and turbo guys add to this thread re no ims failure.

Take note that the original request says "IMS failure for your 997 car, Y or N? tell us (yr, 997.1, .2, m96, m97, failure mode)".

What you find funny is an expected outcome from anyone who isn't fully aware of all the IMS details already and responds to the poll without first reading the hundreds of posts here.

I dont get this my car was built in july of 06 but yet i have the small bearing unless the dealer i went to are morans.

how do you know it's July 06 build? Vin number? Engine Number?

how do you know you have the small bearing? you have to take off the transmission to check which is a big job.

I had the car in the dealer last year for the alt cable to be replaced and when it was there the service manager told me my car has the 996 bearing or the smaller bearing. The date of birth of my car is july06 its a 2006C2s. The dealer never opend the case but i would fugure the manager would know.

Damn the cars at the shop for a few weeks i remember looking at it it was very faint. Is there any other number i could look at? The price tag paper the car came with maybe?

I am looking at an 06 911S with 36K miles. It had the IMS and clutch replaced under warranty. Is this a major red flag? Should I move on to another car? Thank you for your input!!!

Well - first of all the IMS is the InterMediate Shaft. That would not have been replaced. It's internal to the engine and it can't really fail by itself. It's the bearing at the end of the shaft that is known to fail - and sometimes the flange at the end has been known to leak.

They either replaced the InterMediate Shaft Bearing (IMSB) or they simply replaced the Intermediate Shaft Flange. First thing you have to do is verify what work was done.

If they replaced the IMSB - then that woul dbe a good thing (obviously) because that's a job you won't have to do yourself.

If was only the flange, then you *may* want to avoid the car because you will want to replace the IMSB at some point....depending on your ability to deal with anxiety.

Obviously a new clutch is a good thing in either case.

I'm not sure why a new IMSB and a new clutch would be a reason to avoid a car. Perhaps you can explain that to me.

You're not the first to ask that question - but it always confuses me when people do.

check your certificate of authenticity for the engine number. with that said there has been indeed reports of march05 onward cars popping up with older/smaller bearings.

Sorry for the dumb question but what certificate? The window sticker?

Easier to just look at the engine itself. lay behind the back of the can and look past the exhaust at the engine. You can see it without jacking the car. It's stamped right into the engine block.

2006 4S, 40k miles, no IMS failure so far
2007 2.7 Cayman, 60k miles, same

Engine number from rear view. You can see it without jacking the car.
