Anyone know how to find out if an engine is original to the car or a replacement?

 

your Porsche certificate of authenticity will have the original VIN + engine number on it.

compare the engine number to the one on your engine via checking underneath the car...

 

I think if you can't verify through the dealer network if the motors been replaced, a Certificate of Authenticity might be the only way.

 

I thought they put a X somewhere in a rebuilt factory engine number.

 

I'll try to find out first hand from a buddy getting a new engine put in right now.

 

You can order a VIN report from Suncoast which was about $10 or $20 and this report will give you your original engine number (along with a bunch of other specs). Then you can look at the engine number on your engine to see if they match.

 

IIRC....If it was a factory replacement motor, there should be an "A" in the block stamp.
The "A" is for the German word for replacement or something like that.

 

Correction should have "AT". German for exchange

 

100% confirmed, windyCityC2S is correct.

i am looking over the paper work of my friends replacement engine right now.

M97/01ATXXXXXXXXXXXXXXX

with that said there are no "X" in the engine number.

 

Thanks guys
