Replacement motor verification?

[Reborn996]

Okay, I ended up buying a 2001 Carrera Cab earlier this year with about 85k miles on it. When I checked the motor is seemed very clean, all the way down to the nuts and bolts looking new and the wiring harness looking new. My thought it that this car has had a motor replacement done but the dealer did not have any service records for it. Is there a way to check to see if the motor was replaced? Maybe a part number revision?

Check the serial number on the left rear lower engine case.

The engine code is on the driver side of the block just below the #3 cylinder exhaust header. I find the code hard to read without putting the car on a lift. I had success using a digital camera to photograph the code and was able to read it that way.

If your engine has "AT" in the code like this: M96/04AT66***** it means your engine was replaced. Some people view this as a plus, but it usually means that you have an IMS bearing that cannot be replaced without a full engine tear down. This probably means no LN Engineering retrofit option for example.

Clarifying Loren's post. S/N is on the drivers front side of the engine, near the rear of the bottom of the oil pan. You might need to scrub the plate off with a wire brush and some degreaser (wd40 for example) to see it clearly.

Weird, I was looking for this post and could not find it so I reposted... Sorry about that everyone.

I did check the engine number and it looks like it is not a replacement version. I recently did the IMS bearing retrofit when I had the clutch put in so it makes sense. Is there any way to find out the production date for the part number listed below?

M96/0466104581

Guess I will have to order the Porsche certificate of authenticity so I can see if it is the original motor. :)

M96.04 with prefix 661 is a MY2001 3.4 liter engine - 299 HP.

Thanks for the confirmation Loren!
