Please keep us posted on how it turns out.

Hasn't this issue been eliminated w/ the latest gen (997.2) model?

My father's friend had an IMS failure. It was an 03' turbo, w/ only 28k on the clock! Owned it since new. It happened during the 6th year of ownership. He actually wrote Porsche (in German) hoping they would cover the repair costs and they instead offered him $15k off his next purchase. He told them to shove it! lol

'05, 58K miles, no problems

No IMS issues _ 2005 Boxster with 52K miles and 2006 997 with 20K miles on the clock

2005,IMS failed @ 40,000. Purchased @ 28,000 miles. Started car and heard the death rattle. Local indie repaired engine with new L&N for $ 7500 Car runs great but now having problem with mis-fires @ low rpm. Fuel injectors due to ethanol ? This is my 1st 911.Blast to drive but not impressed with quality.

05 C2S with 51,000 on the clock. No problems.

Pulled the motor last year (about 48,000 miles) to do the LN Engineering upgrade as a preventative measure, but discovered that mine was a late enough model in 05 to have the upgraded IMS from the factory. Replaced the RMS due to a bit of a weep at the time. Clutch was A-OK.

Sorry all, my car is a 2005 (fairly early production... I'll revisit the production month and update this). The dealership replaced the engine already. Whether or not PCNA was going to be responsible, it had to be fixed, so I had it done.

I'm currently moving from Georgia to SoCal, so things are a bit chaotic, but I plan to readdress this with PCNA. If anyone has any advice for dealing with them, it'd be greatly appreciated.

I'd be most interested to hear from anyone who was out of their basic warranty period and still had PCNA provide a replacement engine free of charge. I'm under the impression that there are a few of you here and from RennTech.

2007 C2. No IMS failure.

Bump. I believe we've got about 7 IMS failures on record as some of the "yesses" are from other models etc.

2007 C2, 50,000 miles, NO IMS failure. (was inspected a few weeks ago and found to be in perfect shape)

Many blown engines here, there´s a dedicate blog to it.

Reiterating the orgininal intent of this post so newcomers see the purpose of the poll without going to page 1

________________________________________________________________


Many have been asking to understand how many of the 997 cars have had IMS (intermediate shaft) failures. Although the people on this board are not necessarilly a random sampling of 997 owners I would like to see a poll to get a better sense of it.

• Please vote only once for each 997 you own (yes or no).. you can post multiple times but only vote once
• Please include details of your car and engine if it failed via IMS (m96 or M97) and when.
• Please let us know if there were any mitigating factors (low oil, overheat, etc) that might've led to the failure
• Please post only about IMS failures, this is not about RMS failures etc.
• Please post only for your car, no heresay or posting for a friend who doesn't frequent the board
• Please post what was done to rectify the failure if your car failed (CPO engine, engineout of pocket, used engine, sold, insurance fire, pushed it into a river etc)

Hopefully this will help owners and soon-to-be owners get a sense of how frequently this occurs.

Extrapolating fail vs non fail numbers from the poll taken in response to this Renn thread it would seem that a blog dedicated to those engines that did not blow would be much much longer. I did look at the Total thing a while back. It seems to reflect a trend in the early 05 motors that is troublesome. If I had such a motor I would be looking for an opportunity to replace the bearing for the sake of my peace of mind. While the percentage of failures is low it must be a devastating experience. Fwiw I did own an E46 M3 during the time of the main bearing replacement/recall. I never learned what the failure rate was but it was a class act on BMW's part.

76k miles on my 2007 997.1 C2S and still no problems with IMS or RMS. Still uses only about 1 quart of oil between oil changes (5k miles). Still drives like a dream. Still love it. Know I should sell it, but can't quite bring myself to list it anywhere. Mine seems to be bulletproof.

Why should you sell it?
