What you recommended works too as I did have the VIN ran, which then also confirms the engine has been replaced.

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.

POST 1 / ORIGINAL POSTEROriginal post

I just picked up a 2003 996 and the previous owner stated that Porsche told him that the engine had been replaced at some point and that the IMS bearing was also fixed at that time. They didn't provide him any documentation nor did he ask for any. Is there a way for me to check an engine code on the block to see if this is true? Or do I need to make a trip to the dealership to see what information I can get from Porsche? Thanks in Advance!

POST 2Original post

Post the engine sn number. There is a way to generally decode the motor but there is no tracking via porsche that can tell u if u have "matching numbers" or what vin the motor came from. A trip to the dealer will get u nothing.

Where would I look for the engine sn?

POST 4Original post

Engine serial number is left (driver) front corner, just above corner of sump plate. There is a small 2” x 1/4” flat spot with the number tapped in. Replacement has an “AT” stamp following the M96/0x. Next question will be for you to determine, if the engine is a replacement, if the IMS is the non-serviceable bearing. You can try to get any records from Porsche dealer, but don’t hold your breath.

POST 5Original post

I did get info from the dealership regarding my engine, so if you get a knowledgable parts guy, they can do some digging. Unfortunately, a good parts person beind the counter is hard to come by. However, not all replacement engines will have 'AT' in the serial number, so this is not the definitive way to determine if you have a replacement engine. Ask me how I know ...

POST 6Original post

drivers side - iirc get an old toothbrush and some soapy water I don't see too well these days so I wiped it with some red paint

POST 7 / ORIGINAL POSTEROriginal post

Found it. It is M96/03AT66569080 which looks like it does have AT in the SR.

I thought VIN analytics gives you the engine and trans serial numbers....

POST 10Original post

Not true actually. Porsche has all the original info, including engine serial number, on their vehicle info pages for any particular VIN. I got my sheets from a friend who worked at a Porsche dealership in my dealer group. It's also how I was happily surprised that the motor in my earlyish 99 is original.

I guess ill ammend my answer then. If u have a friend at porsche u can get the info. My dealer was not able or willing to get me that info. Not sure on vinalitics as my vin does not produce any results in there system.

All good of course! Here is what the screen looks like. My engine is the same serial number stampes as indicated on the spec sheet. EDIT: Added pic of mu motor serial for good measure!

POST 13 / ORIGINAL POSTEROriginal post

Thanks everyone for the feedback!

FWIW Suncoast Porsche will send you a full decode with options and serial numbers for $10 https://www.suncoastparts.com/product/VIN.html

I use https://vinanalytics.com/ for the same thing and it's free.

For my 99's it cost $8.99. It's instant email though. I'm very happy with the money spent and the service.

That's neat, really it is. But VA doesn't give serial numbers and also doesn't have data on lots of 996.1s but thanks for playing.

What's funny is that was the OP. He asked the question, then comes back with a smarmy comment to someone trying to help him. I'm so confused! He is a new poster.

POST 19 / ORIGINAL POSTEROriginal post

Quotes source post: 17887842

I asked about the engine, not the vehicle VIN. I also didn't ask how to decode the vehicle VIN. I appreciate the additional offer for help but it wasn't what I asked for.

POST 20 / ORIGINAL POSTEROriginal post

Quotes source post: 17887736

For $10 I'll check it out and compare what VIN Analytics shows. I was given VIN Analytics link by a close friend that has had a bunch of different Porsches and uses it for when he is shopping for his next one if he doesn't buy new.

POST 21Original post

Quotes source post: 17887866

Is it me or......Let me try explaining this again. For $8.99 you can run your vin and it will show you what ENGINE AND TRANS NUMBER YOUR CAR ORIGINALLY CAME WITH. The results come back in about 1 min. I gave you the website, choose the appropriate option to buy and wait 1 min. It's an awesome service.

POST 22 / ORIGINAL POSTEROriginal post

Quotes source post: 17888472

It's both of us. I got what I needed before you chimed into the post only because I got lucky and my engine sr had AT in it. What you recommended works too as I did have the VIN ran, which then also confirms the engine has been replaced. It was an awesome service and sorry if I came off rude. Thanks for the info so I could confirm what I say with my engine sr.
