Based on the engine failure thread, seems like ALL engines have defective lubrication (newer ones less so), meaning all will fail prematurely (compared to a non-GT engine)... but on a non-tracked car with a G engine, it might never fail even under a prolongued ownership. Now, as for the letters, E means 2014 (all replaced), F 2015 and G 2016. But even Gs have had further improvements starting in July builds, with DLC coating on cam lobes (early Gs only had the rockers). And G engines have a much improved oiling system, so if I were you, I'd only buy a non-tracked car with a G engine AND extended warranty. But that depends on your risk tolerance. Mine is very little for that kind of thing
, so no 991 GT3 for me. Good luck.

The subset of owners having serious failures on track are a very small percentage of the number of GT3s used for track work.
I know of a number of owners that regularly track their '15 GT3 and run them as they were meant to be run at the track. No issues.
07 to '11 GT3 motors had their issues too and issues with over rev concerns.
Any engine regardless of manufacturer subject to the increased stress of track and/or race conditions will have a higher risk of failure.
Case in point, Z06 track failures due to overheating, GT350 recall due to faulty oil line connectors causing fires....
No car is immune and cars in the future will have their issues too.
GT3 is a great car and will more likely than not be trouble free with street and track use as intended with proper maintenace. Of course you should make sure having a good warranty as you would do with any high ticket car.

Easy. Open your engine cover and check your engine serial number. If it's above G05374, you have the latest upgrades. I got this info from Macca's engine failure thread (with a gazillion pages), by the way. Good luck.

My Chevy Silverado in school had these crazy oiling issues, also the 5 lug wheels which required a special English Allen wrench which always rounded the bolts.. trip to the dealer each time to change a tire... Not to mention the door seals, let me tell you about those.....
Full disclosure: 30 years later I did get an Audi A6 with a CVT. It was a very reliable car but I gave it right back after I experienced CVT angst. Now, my DD is an S7, so far one of the very best and most satisfying cars I have ever owned. Unreliability is not in the eye of the beholder, it is when u have to call someone to come pick u up!

I own 2 GT3's both heavily tracked and both had engine replacements at aprox. 18k. Last one was replaced a few months ago and after 2 track events it went back for trans leak twice and I will pick it up today with a new PDK, thank you Porsche!
