Just picked up a '99 C2, and can't find the history from 0-45K miles (has 65K now). I assume it's the original engine, but would like to know for sure. Searched the archives, but could not find anything on engine stamp/date codes. Surely there is one somewhere and you can tell the year of manufacture. Anyone know?

There is a SN on the bottom driver side stamped to the right of the 1st header tube (furthest one back away from the bumper). Don't know how to decipher it or what it will tell you. There is no VIN on the engine itself. If the car you are buying has a replacement engine; many would see that as a positive thing not a negative one.

Here is some info from the PET. Maybe this will help. So your engine number would begin with 66X followed by a 5 digit serial number.
It is my understanding that if the engine has been replaced with a remanufactured engine, there will be a 'AT' at the end of the serial number.
Edited: I had originally had 'X' as the remanufactured engine designation, but it is in fact 'AT'

But I'm not sure the X tells all because my engine was replaced by the Porsche dealer under warranty at 13K miles, but I don't believe I saw any special number/letter designations, but then I don't fully recall and likely will be too lazy to check anytime soon.

I believe Porsche has replaced the 'X' designation with 'AT', for instance the 2005 built reman engine sitting in my garage has the following serial number M96/03AT66565160.
Do a search over at Renntech, you will find more information on this as well as several pictures of where to look for the serial number.

Hint: Looks just like the rear pic of yours, but the rear spoiler appears to have come from "south of the border".......
It's squeezed in the garage right now, would make an ugly !@#$#@!
Gotta go to Chicago tomorrow for the weekend, but will get the !@#!$! up next week!
I LOVE it! (it's my first P)
And as Big Gay Al would say : "Thanks for asking!"

This same thing came up in another thread today and another Rennlister wanted to know if I was 1) sick, or 2) on drugs, or 3) had just gotten laid (you can rule out #3, at least until my wife goes out of town

Sorry to resurrect this old thread, but I am curious as I just found out that my car has a new engine in it. The serial is m96/0318AT66568904. Its an 03 C4S w/41k on it. The documentation from the previous owner didn't have any info on the new engine. From above, I understand it was the most recent "revision" of the 996 motor for 2005, but does the end of the serial number offer any insight as to when it might have been installed?

My info is the serial number is a sequential number applied when the engine built not when it was installed in a car.
If you want to know when the engine was installed if you know the dealer where the work was done a call to the dealer with the VIN of the car should have this info in your hands.
My experience is if you approach a dealership with the right frame of mind it will share with you when the car was serviced. You should avoid asking for any details about the owner. All you want to know about is the car.
If you don't know the dealership but know the area the car spent time in -- based on perhaps a CarFax report -- you can just start calling Porsche dealers in the area until you hit the one that serviced the car.
If the engine installed by an indy...well, I have no experience tracking down any servicing done by indy shops.
Sincerely,
Macster.
