How To Know If The Engine Has Been Changed

Recommended Posts

I have a offer for a 99 996 c2 Tip with 30,000 miles on it, and i´m wondering if the Engine of this 911 is been changed.

Is there any way to find if the engine has been changed other than goin to the oficial Dealer??

Thanks in advance

I believe only the dealer can tell you (if it was done by Porsche.)

But the reman Porsche engines have an additional letter or number at the end of their serial number stamped on the engine. Once you have that information you can look at the serial number on the engine of the car you are considering.

Do a search here and you should find the thread with that information.

This applies to ALL replacement engines.. it is VERY simple to determine if you have a replacement engine or not in your car :)

The replacement engines have NO (I repeat) NO cosmoline on them :) The cars (all Porsches) get sprayed with the cosomline as they go onto the boat for transport to keep corrosion to a minimum during the salty sea voyage :) Replacement engines from Porsche are shipped in a crate and never get sprayed :)

Want to know wha you have? LOOK underneath the car. Look for the cosmoline on the transmission.. lower suspension plate.. suspension pieces.. you name it.. if the engine has NONE on the oil pan or the sides of the block.. or on the bottom of the heads near the exhaust ports (it is sprayed straight up towards the bottom of the cars) then you have a replacement engine!!

Simple :)

Unless you have an engine from a wrecked 911/salvage yard (which would still have cosmoline).

Look for the characters AT in the engine number for factory rebuild as quick check, for more detailed info ask your dealer to check the original factory delivered VIN-engine number configuration. OPC also listed in the car's manual.

PhillipJ - I thought you only donated $8,500 to the Porsche gods (for a 3.6 which we all know is now less of a contribtion to the Porsche gods than a 3.4) and the rest went to the ROOCK gods. It must be nice to have so many deities to worship and tithe to!!
