And engine serial number?

 

2005

 

2007 997.1 C4. 45,000 miles and no engine problems at all.

 

I have had around 15 cars with M96 or M97 engines, average mileage was around 100k miles. No issues with any of them. I replaced the IMS bearing in three 996's at over 100k miles, just to sell them. All of the old bearings came out in perfect condition.

 

Lucky for you. 10% are not so lucky.

 

2011 997-2 C4S no IMS , CEL on now

 

2007 C2S with 52,500 miles. No IMS issue

 

You don't have an IMS

 

I've owned 4 911's that use the IMS bearing. They have been the most reliable cars i have ever owned.

-2005 S launch edition i had with 35k on it when it got totaled no IMS failure.
-my new 2005 S with 78k on it now no IMS issues
-owned a 2002 996 drove to 65k then replaced IMS when it was time to do clutch just for peace of mind & since they were in there anyways.
-Owned another 2002 996 C4s with 70K miles never replaced IMS and no problems.

 

2008 997.1 C2. 50,000 miles and no engine problems at all.

 

2006 997.1 Carrera S. 52,000 miles no issues whatsoever. Oil changed once a year

 

2006 997.1 S 3.8 with 145 000 mile on it NO IMS failure

 

2006 997 c2s 70,000 plus miles. No issues.

 

2006 997 C2 Cabriolet 84,000 miles. No issues.

Is there any way to tell whether I have the smaller or the larger bearing without performing surgery? The car was built in January, 2006.

 

2007 C2S 81000 miles. No IMS problem (yet).
