bizarre engine number - 964
Yo! My ROW C4 cab has a bizarre engine number - EH2010991. Course it should be 62L*****. Now there are two possibilities: 1) The cars a ringer and the engine is from a stolen vehicle; 2) The engine has been tuned or altered in some way and the tuner has added a new engine number. If it is option 1, then why go to the trouble of grinding out the engine number, but not replacing it with the original number? Oh boy! What a mess! Any help would be appreciated. Is there anyone else out there with an EH engine number?

The engine number also appears on the options sticker stuck to the underside of the trunk lid. What does that one say?

Cheers, Don. Yes my car has that sticker with a 62L engine number. So why would anybody bother stamping a different number on the engine?

I have no earthly idea. I assume the title is clear and the motor looks "correct" to your eye.
I'll check thru Adrian's book on the 964 and see if there is any reference to special engine numbers.  Don

Thanks Don. I've even emailed the man himself and he's as perplexed as me! My next step is to go back to the dealer that sold me the car and ask if he knows anything. I've also spoken to one of the previous owners who knew the engine number did not match the ID plate or the registration document! I guess it's my fault for not checking before I bought the car. Having said that, it's a lovely car - fantastic performance compared with other C4s I tried so I'm really hoping that I've got some sort of tuned engine! Cheers!

Just heard from Adrian Streather. His best guess is that, at some time, the engine had a replacement crankcase half. Apparently they come with a factory ID stamped onto them. The dealer doing the job should grind off the factory ID and replace it with the correct engine number (taken from the ID tag in the luggage compartment). I will double check this with Porsche GB but it sounds right to me - especially as the engine has been modified (head gaskets, solid flywheel etc.). Cheers and thanks for the help.

a original replacement case does not have any numbers stamped on it .
It is not unusal that a Motor Shop puts his own Numbers on the Engine to identify it later in case of Warranty Claims . It is very much possible it is a exchange Engine from a private Company. I would try to get a statement from the Dealer that this Engine was in the Car when you bought it . Harald |

Good point, Harald. Yes, I'll get the dealer to do that - or else I could try what Porsche GB suggested: grind the number off and then re-stamp the original! Cheers and thanks for all the help you Pelicans (whose beaks can hold more than their bellys can!).
