I can't recall seeing an IMS failure in a later 987 or 997 with the updated bearing. Not saying that it has NEVER happened, but I think it's very rare.
Here's some light reading if you are really bored: https://dl.dropboxusercontent.com/u/93289189/Porsche_Engine_Codes_1952-2012.pdf |
I've mentioned before that I have a friend with a 2006 997S that is on its 3rd engine, all paid by Porsche. All IMS failures. Engine #1 blew under warrantee and then the replacement engine blew and they ate it out of warrantee. So far so good on mill #3.
