How many 15-16 gt3's have engine replaced?

Im over 6000 miles on the new replacement G. On the road it uses next to no oil (maybe 250ml over 4000 km). Thats with a number of spirited 9000 runs. On the track I use approx 125ml per track day (150 miles/100+ minutes). The first 4 track days I probably only used 80-100ml a day but it has stabilized at 125ml.
Craig, your oil consumption is abnormal. I recall another g engine replacement (or was it a newly delivered g engine RS) also reported on these forums to be using alot of oil but we never heard the outcome (may have just been a dodgy read out).

His plan is to get a new engine but I don't know the status of the case as of now.

I had a rebuilt engine for a week before they installed the new one. The old engine with the rebuilt heads felt way stronger than before. That is to be expected since the new heads were actually firing all cylinders and all valves opening correctly. I was amazed at the difference in power and ability to rev. I found myself spinning the tires at stop lights due to old muscle memory. I suppose the slow loss of power from worn cams was so gradual I just adjusted to it. Thinking back to my last Sebring event I remember thinking it was odd that a similar red GT3 was able to pull on me between 5 and 7. Hindsight tells me I should have been investigating the power loss.
The new engine is very tight, and I am following the break in procedure, not exceeding 4000, so hard to tell about power. It seems to rev slower than the rebuilt old engine, but I believe that is the difference between a well worn in engine and a new one. I am reserving judgement until it is broken in. I have my first track event in January and that tell me if this engine is a keeper. Taking it for an oil change today and will get a sample.

I think one way to know is to check your top speed on the fastest straight at your track (assuming you have Harry's or another laptimer) - aside from very different weather conditions or braking points, that speed should be pretty close over time if no power loss.

Good point, and will do.

Some good news.
Wrote a very detailed letter to my Porsche dealer today detailing my case, the fact that it was a known problem, that I was not given advance notice that I may have to pay, how much money I had spent on PCars in the last 18 months, highlight the track warranty conditions in the booklet that I had complied with, etc....and that if they did not positively resolve the situation I would marshal social media globally via Porsche forums.
I sent the email to my dealer at 1pm. My dealer forwarded it to PAG at around 2pm. Then at 5:30pm I got an email from my dealer saying that PAG had agreed to do the work under warranty.
Faith restored, if a little tarnished.

Seems I am very late to the party (but then again, no GT3 street car for me since a long time ), but when I had an oil leak on my 997 3.8 GT3 engine, they tried fixing it 6 times. After the 6th time they just gave me a replacement engine, free of charge. This was in Germany, with a car I didn't buy at that dealership (bought it off the showroom floor from a dealer 800km further), with at that point in time 50.000km on the clock and a lot of track use (which you could tell by looking at the car. Rubber marks, alignment, sandblasted wind screen etc.). They never even mentioned or asked if I tracked the car.

The biggest issue was that under normal street driving all was fine. It only started spraying oil on one side of the engine (and the rear bumper ...) when driven hard on track or when doing 300km/h on the autobahn (high oil temperature situations). Very hard to reproduce, and the dealership even refused to test the car to see if it still happened after the repairs, telling me they are not allowed to drive customer cars in that way (which I perfectly understand). I had to go and drive flat out on the German autobahn myself to conduct some testing
Mind you it was a very small oil leak. Nothing that would throw a puddle of oil on the road or make my engine run low on oil. I guess they sent the engine back to Porsche. Too bad I never heard what the actual problem was.

Just checked the replacement parts catalogue. Seems they changed the valvetrain parts two times:
- new heads, new valve springs, new camshafts starting from engine F 03048 (must have been in early 2015)
- new camshafts (intake and exhaust) starting from engine G 05373 (mid 2016?)
- new heads, new valve springs, new camshafts starting from engine F 03048 (must have been in early 2015)
- new camshafts (intake and exhaust) starting from engine G 05373 (mid 2016?)
