2008 C2S - CORRECTION: Only the Rear and IMS "seals" were replaced, not the bearing. The dealership noticed oil leakage at 13,336 miles in March 2013 and replaced both seals.

Hello TV911, look at your engine number stamped near the bottom edge and visible by looking under the left side of your car. I believe that if the number starts with M96... it has the smaller bearing and if it starts with M97... it has the larger bearing.

WRONG! Not even going to say why at this point. When I say "I believe" in discussing something with my boss , I get get shut down very quickly until I come back and know the facts

Well 'Sporty', I stand corrected and apologize for not confirming the info.
With that said, man up 'Sporty' and let all of know the correct way to determine the bearing size. Saying "Not even going to say why..." is just...

Ok ok Harv. I just get frustrated because this m96/m97 is a very common misconception along with 'all 2005's have the smaller bearing' (not so, good chance those with build date Feb/March 2005 and on have the larger more robust bearing with almost no failure rates. However that is not 100% true, but as close to a valid generalization that one can make. Some m96s have the larger bearing, i know this as a fact because mine with a build date of 03/5 is an m96 with the big bearing - visually identified. I am unsure, however, if some m97s can have the smaller bearing -perhaps someone else can chime in. If you do a search on this thread and others here on Rennlist it is all discussed in detail several times by some knowledgeable individuals. Sorry if I was a little testy - long day at work

If the center nut of the IMS flange is a 13mm hex then it's the old style bearing. If it's the 22mm nut then it's the new larger bearing.

IMS bearing fail - 2006 997 w/ 32K miles and otherwise in mint condition!
Now what??? Engine is just before pulling a grenade according to my Porsche mechanic, who literally showed me the metal in my oil and filter. It was shining like flakes of silver. Made me want to puke.
Does anyone have a recommendation other than the obvious "Go buy a new motor" ??
Thank you very much..
