Is there anyway to verify if an engine is rebuilt from porsche via visual, eng #'s etc, if no paperwork is present.

Why no paper work?
That is the crucial proof, right?

I haven't heard that Porsche dealerships rebuilt engines (3.4 & 3.6) they order a brand new one from Germany... well in Canada that is!

If there's no paperwork, you could inquire as to where it was done (independant garage or dealer) and then contact them to confirm and have more details...

Try a search, here or on Renntech. The engine's serial number is stamped somewhere around a header tube, and if it's a reman the number has an X at the end, or something like that, as far as I recall. But don't trust me. Plenty written on this, and pictures over on Renntech, I believe.

I must have used wrong keyword search, but thanks just what I wanted to know.

if it's replaced under warranty, u can call 800-porsche

Mother

Not sure if it was. The eng is out of a salvage car what is it they can do for me?

porsche normally re-builds engines when replacing a customers engine under warranty. i have not heard from anyone here who has received a brand new engine from porsche. as long as the block is re-useable porsche re-builds them with the latest engine modifications and up-grades.

Mother

Got me wondering when rebuilt from porsche do they mark with "AT" or XX etc to show this or is this just for replacement engines?

If you have a CoA for your car from PCNA, the original engine serial number is listed, making it easy to check.

I learned it from here, yes, they stamp the block's S/N# with an extra letter. Dont remember what letter it is, but I think Bruce is right.

Mother,

When I was searching for one, I found that the markings of the engine SN# with anything telltale was in-consistent at best. My advice is to not take any "dismantlers' word on anything. I can give you an earful. They are overly optimistic about the condition of things and what it includes. If there is no documentation of it being a reman then price it and treat it as a used engine with the mileage shown by that cars particular VIN. The burden of proof is on them to sell their used item.

My experience so far was an engine with 1 of the headers crushed and one side of the PSE just plan missing. Don't even get me started on them calling the engine an x51 when it ended up not being.



And the last bit on pricing... 50% of what you would pay for a reman with warranty... no more.

Paul: The guys that have this engine rebuild porsche engines, but that being said proof is proof and agree with you. The engine does come with 1 year warrenty but even with that if it makes it a year it still could be a high mileage eng that made there warrenty period, hense the need for engine check along with verifing the integrity of the person selling.

Mother

What is CoA? and will they run the Vin without ownership validation to check numbers?

That's not quite correct.

Porsche provide a remanufactured M96 engine from stock as the warranty replacement for your dead one.

Ask me how I know.... twice!

The remanufactured blocks are ones that initially failed QC at the factory, and were then disassembled and remanufactured to meat the QC spec.

Early failed M96 blocks were returned to the factory for QC checks, so they could figure out why they were failing - porous block, cracked head, slipped cylinder linings etc etc - Early RMS failure engines were also returned to Germany as they believed they has an issue with 'out of round' tolerances leading to the RMS issue. This has since stopped and RMS repairs are done at the dealerships (a lot!).

Dealerships therefore treat the engine as a swappable module, rather than a possible tear-down repair option.

There are of course specialist shops that do tear-down and repair on M96 - but most dealerships do not touch engines to this level these days.
