The Porsche dealer who did the work has purged their records from before 2010, so they can't help. After I bought the car a few weeks ago and went to get the IMS bearing replaced, among other things, the shop told me they couldn't do the job without splitting the cases. That indicates the motor is post-2005. But, maybe not.
At least two factors are involved here: Porsche made running changes during production of the M96 motor that included various IMS bearing versions, and then introduced the M97, which has a "captured" IMS bearing. Early M97s may also contain a weak version of the bearing. Documents in the successful class action lawsuit against Porsche based on IMS bearing failures contain some clues, but do not reveal everything Porsche knows for obvious reasons.
I'm determined to get to the bottom of this business and will start a new thread when I have the facts.
Cheers,

Thank you Dave. I had a PPI done and the dealer who did it said at 49,000 miles and the way it's been maintained it should not be a problem with the IMS. The date of engine build was July 2005 for model year 2006. Is it easy to just look under there and see if it's the replaceable bearing or do you need to take stuff off. Getting the car this weekend.
