His maintenance scheduling for lack of a better term will enunciate the type of engine his car has.
For example, my 00 C2 has:
996 110
M96 04-66Y G9600-10
L92U, & so on ... for each of the options the car has.
The Indy should have looked there first to find out what type of engine the car had in the 1st place.
I believe that car is more late production than early (Aug to Dec build) which might explain why it has the bigger internal IMS bearing but I'm on soft ground here.

there is a slim chance, although unlikely because any work done would've been cover under warranty and documented. I went though another discussion dedicated to the IMS topic (https://rennlist.com/forums/997-foru...lure-mode.html) and it seems like a few 05 997 c2 owners have the same updated m97 engines as well.

fanny, I dont think I will be able to convence you over this forum. if you want, call LN Engineering or your dealership, and they will verify the fact that there is no way of accurately determining through VIN, engine number, or build date. Dropping the tranny and visually inspect the IMS is the ONLY way to know for sure.

I think I am a little confused as to the M96/M97 designations.
With that said, the clearest way I can put it is I have a 2005 3.6 engine, with a M97 design IMS bearing.
Here is what I found from LN Engineering website
"MY02-05 will need a single row Retrofit™ kit, although depending on how late the build date was, there may be some MY05 vehicles with the updated M97 IMS, which is not serviceable, at least without teardown of the engine."

This is a different perspective on "early" production. The 05 997 was introduced in mid 2004 and I would estimate that production started in the late spring of 2004. And 2006 MY cars were probably being produced in late spring or early summer of 2005. So I have always considered early production MY05 cars to be those produced in 2004.

Just to clarify you have a larger "single" row bearing. They stopped using dual row bearings after 2001. If you indeed have the larger bearing then just drive it and enjoy.
