Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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

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.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

is there any documentation about engine numbers? Before I go dropping 4K into this engine I woudl like to know a little about it. Is it the original engine? for starters Can anyone guide me in the right direction? Thanks

POST 2Original post

If AT precedes the serial number, it is factory reman. 1st digit is number of cyls 2nd digit - 6 is for normally aspirated, 3 is for GT3, 4 is turbo 3rd digit is production v=1997, w=1998....5=2005 4th thru 8th is serial number

POST 3 / ORIGINAL POSTEROriginal post

what about serial numbers for production years?

POST 4Original post

What's your year and model type? There are a whole boat load of numbers to sort through. Two example's for 99: 99 coupe, USA import, Engine #'s go from 66X00001 and up, 99 C4 = 68X00001 . Huge lists and depends on if it is a C2, C4, Cab etc. Also big production numbers. 1999 C2 = 10728 Cab's = 9458 C4 = 4773 C4 Cab = 3081 So just for Y 99 your looking at 28040 installed engines, less the 20 thou alleged IMS blow up's for that year. <sarcastic mode on> Total MK1 production - all models = 85556, MK2 total = 89706 As long as your engine has the correct VIN# for the year and doesn't have an X it *may* be orig but the sticker under the front hood should match the engine VIN stamped on the block. The cardex service that you have to pay for from Porsche will list all info for your car such as options and serial numbers.

POST 5Original post

Kyle PM the serial and I will see if I can decode it for you. Woohoo, mine's a factory rebuild

POST 6Original post

Another check you can do is the engine model against the year and model of your car. That info is under the hood and the engine model # will begin with M96/xx and then a space and then another three digits. Your ECU read out will also tell you the engine number that was flashed at the factory that you can check against the the engine stamping.
