Replacement Engine
As Jake Raby has reported, the engine number is etched on a sloping panel on the crankcase, per the attached pic. On my engine, the numbers are hard to read, but come out as:
M96/03 663 09588
- The M96/03 is the code for the 3.6 liter 996 engine
- After this, there are 8 digits, of which the last 5 are the specific serial number of the engine.
- The digits "663" stand for: the first "6" = six cylinders, the second "6" = normally aspirated engine, and the "3" = 2003 year of production, as I have reported earlier.
The above deciphering comes from page 559 of "Porsche 996 - The Essential Companion", see attached chart.
The above is in agreement with what Macster has reported earlier in this thread.
...Rickker
M96/7064301466
Engine is in my 03 Turbo with AFAIK with the orignal engine. (Car had just 9500 miles on it when I bought it June this year.)
Sincerely,
Macster.
