Performed · outcome unconfirmed
My clutch was replaced by the non-Porsche dealer just before I purchased the car, and the shop did NOT replace the IMS.

Suggestion
Perhaps the letter A is for engines repaired under warranty but after sale, and the letters mentioned in the article might refer to work done before the car left the factory or for engines reworked by Porsche before they even went into cars...which I think Jake referred to.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Yes, it is more or less likely you have a dual row IMSB
This subject has been discussed numerous times
Do a search and you will find the answer you seek grasshopper
OK Robman, I will stop the madness.
Check out the last post on this thread. Dude had a 12/99 build date with a double row. So there's you answer.
https://rennlist.com/forums/996-foru...e-mode-54.html
Your VIN says your car is a series Y or 2000my. Therefore it could have either. There was no clear cut off from double row to single row. Only ones for sure, kinda-sorta, to have double row are series X (1999) or earlier. Even then, it is the engine serial that matters as some cars got replacement engines in that time frame.
I have a 2000 model year built in late 99, it has a duel row bearing. Build date of March thru May 2000 is the general gray area. I've chosen to not replace my bearing as the car just turned 50k miles and I'm just not going to worry about it. Just drive the car and let it put a smile on your face.
I'm in the gray area as well.
I have an '01, build date of March 2001. Jake says the factory records are crap, and I believe him. However, my engine serial number is M66113xxxx, and allegedly those after M6611
4
xxxx are pretty much assured to be a SINGLE row. Additionally, (and I'm sketchy on this part...) I believe the class action suit only applied to cars made AFTER May 2001.
So, if you like Russian Roulette, I have a very high chance of MAYBE having a dual-row bearing.
My clutch was replaced by the non-Porsche dealer just before I purchased the car, and the shop did NOT replace the IMS. Whether the dealer cheaped out (likely) or whether the indy shop told them it had the dual-row bearing (as evidenced by inspection), who knows.
I think I'm just going to drive it and not worry about it. It's got 85k on it now and had new clutch , pressure plate and fly wheel installed at 78k by the dealer(previous owner) . maybe next clutch I'll do the ims.
Interesting...read it earlier but saw this new item..."One easy sign that you have a re-manufactured factory engine that has been replaced is if there is an X or Y in the engine number located on the lower edge of the engine�s sump."
I haven't crawled under the car to look, however my COA from Porsche lists the engine number as 66Y07632 (meaning it has a Y in the engine number). The production completion date is 12/15/99. The car was sold by Beverly Hills Porsche the following month as a 2000 model.
That sounds like my engine is a remanufactured engine from the factory, before the car was shipped to the states. I wonder if this could be related to the fire in the factory that Jake Raby has mentioned. I wonder if Porsche Cars of North America will give me a new 911 as compensation...or at least free expresso for life.
Oh well...all we can do is drive them and smile. I'd rather have a blown engine than some disease that sends me dripping into plastic bags hanging under a hospital bed.
John, not quite sure where you read that but it is either wrong or you misinterpreted it. The third letter, after the M96/01 or whatever, is the model year designator. 66Y is a my 2000, X is a 1999, W is a 1998 etc. Yours looks like the original engine. There is a replacement designator but if I remember right it is T, could be wrong on that but yours is correct for a my2000.
That is what I always understood as well. Actually I think it is just the letter A. The thing with the Y came up in the article referenced in my post, and quoted. I was totally surprised to read it. And then there is the Raby comments about the factory fire and possible damage to engines, etc., etc.
Perhaps the letter A is for engines repaired under warranty but after sale, and the letters mentioned in the article might refer to work done before the car left the factory or for engines reworked by Porsche before they even went into cars...which I think Jake referred to. Again my engine number is M96/0466Y7632...but the only thing, in my opinion, that matters in a 17 year old car is do I enjoy driving it. And I do...however I will migrate back to a manual coupe sooner than later.
FYI: AT = German acronym for the word "AusTausch," which means replacement or swap. T would not be capitalized in standard written German, I just did that to show whate the T comes from...
Build date of my MY2000 cabriolet is May 2000, I had dual row, which came out in seemingly perfect condition. I would bet money that, if you do still have the original engine and bearing in your car from 11/99, it's a dual row.
