Exactly how my engine fell apart. It's kind of off topic, because these engines (mine at least) did not get an AT number.
On the other hand, I have an AT engine from a Boxster S which has the non-servicable IMS bearing, and thus definitely different from what it came out with from the factory originally. So, Piper raises a valid point.
