How to determine if the IMS bearing was changed

[CMeSpeed]

Greetings,

I'm told somewhere in Pelican is a list of serial numbers that would tell me whether a 06, 997S has the Porsche upgraded IMS bearing.

Can someone please direct me?

BTW I am selling a pristine 993 C2. For details email me at [email protected]

Thanks,
James

There is no "list" but nor does there need to be. Any Porsche delivered after 2005, any factory reman engine delivered after 2005, and even some 2005 model cars carry the non serviceable oversized IMS bearing.

JFP: Good info. How about this question...I have one of those "...even some 2005 model cars...". Per the original build list still has the same engine at 51k miles. 2005 996 C4S. Any way to tell other than dropping the trans?
Thanks

As we do this for a living, I can assure you that you should not place any credence in published lists of build dates, VIN's, etc. We have found every one of them to be wrong more often than not.

The only sure way to know which bearing is in the car is to take it apart and look; the non serviceable IMS is the only design to use a 22MM center bolt.
