I have a 2002 Boxster (Base) and the engine serial number has AT in it. Actual number is: M96/22AT65265202. I read several posts in this forum that indicated the AT means it was a porsche rebuilt engine. Is that indeed true? I am asking because I am trying to understand when/if it has the newer IMS bearings.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

AT indicates that it is a factory rebuilt engine. Which IMS bearing is in it depends upon WHEN it was rebuilt.
JFT many thanks for confirmation. Is there any way to determine when the engine was rebuilt/replaced? I went to a Prosche dealer nearby and they were really useless.
