Mine went on a track day. I was able to finish the track day by short shifting and not getting over ~8k after I cleared the code. Let it run up to 9k on the last lap, triggered the code and PNH had a new engine in it in a week or so after dropping it off.

there is no set average mileage for failures. I have seen failures from 5k to 65k miles……..no safe zone with these. I just don’t understand how someone would pay todays prices for an original motor car. Serious gamblers

Got mine at 18k and ran it up to 9k everywhere I went. Took me 4500 miles. Couple of track days thrown in as well.

Could the F-Guys please add their exact build date or engine number? There was a significant change in the heads in March 2015. Early Fs are same as E1, late F are half way to G6. Mine is a late one.

I am looking for a 991.1 GT3. I have been through the carfax on nearly all of the cars listed on cars.com - not one of them shows an engine replacement. Is this possible? Are the engine replacements just listed as "vehicle maintenance performed" or "engine performance checked" or would it show up as engine replaced?

I'd love to, but it's gonna be miserably hot out there! Thinking I'll sit out on track days till October, but I'll let ya know if the fomo takes over and I change my mind.

i just looked at my dealer invoice for the engine replacement, and crossed to carfax……no indication whatsoever. Not even a “vehicle serviced” note. Shows you how reliable carfax is if not all dealers or service centers participate

Porsche probably campaigned the dealers not to disclose to the Federal Agency that carfax pulls from.

Do you have more info/source on this?

How does one tell if a given engine is vulnerable? Sorry, I am new the brand and am just learning of the issue.

I have the Carfax for a 23k mile 2016 I am looking at and don't see anything suggesting an engine replacement has been done.

Thank you.

The most foolproof way is to get the car on a lift, drop the rear engine cover, and look at the engine serial number engraved on the engine block.

Engine serial numbers starting with E0, F0, or G0 should be treated as suspect.

Serial numbers starting with G6 are safe -- these are the ones with the top ends with improved cam coatings, finger follower metallurgy, and cam oiling.

The cars are otherwise excellent vehicles and a bargain in the current market if you get one with a replaced engine, or if you blow the engine and get a complimentary replacement from Porsche. In a worst case scenario where you foot the replacement bill fully yourself, you will end up paying roughly the same price as a 991.2 GT3 (in total -- vehicle & engine replacement) for the earlier car.

Good info, @NNayak, thanks. I found within info the dealer provided it's a G0 engine.

Towards end of warranty its a reasonable gamble to have a dealer open it up and inspect for the obvious signs. It will cost you about $6K if they find nothing, but if they do it will cost you $0 and you'll get a new G6. After going into limp mode once my SA advised that they open it up, sure enough the signs were there and they replaced the engine under warranty. My car is a 2016 and had a G engine, one of the last off the line. It had 17K miles on it when it was replaced.

Parts catalogue. The part numbers for the heads, camshafts and finger follower plus some other things changed.

register your car with Porsche NA (they need your vin, proof of ownership, etc). They can tell you if/when the motor was replaced and when the new warranty is good through. The process only takes a day or two. Good luck, most likely it was replaced at some point of its life.
