I have read somewhere that Porsche "re-manufactured" in Stuttgart some portion of those engines swapped out under new car warranty coverage, and such repaired engines then re-entered the parts pipeline.
Leading evidence: 'Repair engines' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean engine picture originates' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Porsche changed over to the single row IMS based on engine #s, not VINs.

The revised/iupgraded intermediate shaft was introduced during the 2006 model year...must inspect IMS flange to discern new design.

2005 started change to larger single row that is in 2005 - 2008 (2005 seems to be running change)

It gets more confusing for the early 997s as the M96 engine was used for these early VINs, so it would be interesting to get your theory validated here as well.
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.

My understanding is there are three types of bearing. I have a 2003 and would be interested in knowing which one I have but I think after 00-01 it's not a fixed equation on what we have. I could be wrong though.
2003 & 2004 definitely single row OEM. 2002 thru 2008 single row. 2005 started change to larger single row that is in 2005 - 2008 (2005 seems to be running change)
We need Jake to chime in here. It's my understanding that you can't tell whether you have single or double row until you actually take it out to look. I've heard that single and double have both been used in nearly all years.
Jake, what's the poop on this?
. Not what I've heard. Double row in MK I only. Reminds me of the 356 threads, where Porsche "used up prior year parts into a new model year design", and the endless debates about which way should I do my restoration...ha ha
2003 Carrera 4S Speed Yellow / 1955 356 Continental 1500 Rust Red
Porsche changed over to the single row IMS based on engine #s, not VINs. Specifically, Boxster engines to 671.12851 (M96.22) and 671.11237 (M96.21) and 996 engines to 661.14164 are double row. Some late MK Is may have a single row IMS bearing.
The revised/iupgraded intermediate shaft was introduced during the 2006 model year...must inspect IMS flange to discern new design.

Relinuca: Your post is worth much more than 2 cents.
Best answer on M96 vs IMS types I have seen in a long time. I would bet you are very close to the truth, here.
I would also bet there are very few 2001 996.1 VINs with the single row, which is prevalent throughout all 996.2s (02 to 04). It gets more confusing for the early 997s as the M96 engine was used for these early VINs, so it would be interesting to get your theory validated here as well.
Ok, stupid question of the year??? But how do you easily tell what the engine # on your car is (besides the stamp on the motor, which I don't know how to find on this car anyway)?
Great pic from alpine003 in re. location of engine serial #. As most readers will have surmised, Porsche relies on engine #s rather than VINs under some circumstances because some number of 996s and Boxsters have been subjected to engine changes.
I have read somewhere that Porsche "re-manufactured" in Stuttgart some portion of those engines swapped out under new car warranty coverage, and such repaired engines then re-entered the parts pipeline. (If true, I wonder if these reman'd. engines were re-stamped with a new serial #. Hmmm)
relinuca
I didn't post the pic but I meant to say "remanufactured" in my previous post as it has the "AT" designation in the engine serial number. To my knowledge, all the remanufactured engines from Porsche in the US has the "AT" designation.
No sweat, Alp!
