Amazing work macca and Chris. You are such an invaluable part of this rl community!! I am curious how this revision will pan out for wear. The new dlc lobe design suggests to me the previously new oiling improvements didn't help enough. Whoopsy described the .2 gt3 engine as another advance forward based in the gt3r so I wonder what that might include. Let's hope pag remains willing to upgrade components for quite some time. With this number of GT cars it could get costly...

Macca, you are awesome. You are really putting the pieces together, and I believe you are on the right track. Well done. A lot of thanks goes to Chris also. Sharing info like this is invaluable. Thank you.
This data paints a very interesting picture. First, having a G engine (MY16 or via replacement) is no insurance policy. You very well may have problems down the road, unless your replacement / rebuild was very recent. Second, this problem impacts a lot of cars, as Macca clearly showed. Is Porsche going to proactively replace the top end on all these cars? I doubt it. Do they let owners know that the engine is covered for this problem out of warranty? If they did, would some people take unfair advantage of this? I think so.
I hate to say it, but I think Porsche just deals with this on a case-by-case basis. You bring the car in out of warranty, see how they respond, and then make a lot of noise if they deny to fix the engine. This is probably the least expensive solution for Porsche, and it has class action written all over it.
Not sure what other options there are, but ideally from a PR standpoint I would really love to get a call from Porsche explaining the situation, scheduling the car to come in to have the top end replaced (and a complete engine, if needed), along with an extended warranty covering 7 years or 100,000 miles, a nice coupon towards the next car, or a slot on a harder to get car (say a 991.2 GT3). If they did this they would pretty much guarantee a lot of customers for life.
We'll see which direction they take on this. I think either way we are covered. The problem is too big. There's no sweeping this under the rug. I would finally add that in no way do I feel less about Porsche, or their engineering prowess. They are pushing the limits. **** happens. It is the nature of the bleeding edge. Keep pushing them, and we will deal with it. Just do right by me, and I will sign up to be a Guinea Pig all day long.

Just logged back on after being offline for 8 hrs....and WOW! Amazed to see how much detective work Macca has done based on a couple of photos and two camshaft part numbers. It is indeed truly impressive work. Thanks Macca.
When I am back at the garage next week, I will try and get a complete list of the new part numbers that are being installed. I think the part numbers of the rocker arms changed too.
BTW, they have brought in an engine specialist who works on the Motorsport and 918 engines to oversee the work. All the guys at the garage are open and friendly so I cannot complain about the first class treatment I am receiving from Porsche.

We were the beta tester but Porsche is Porsche.
Don't forget that this is the most advanced & expensive development program on GT cars which cost 1 billion $ to PAG. Obviously, as every new model you have to face several issues which I found quite limited.
The engine was pushed far further common limits so, as expected, deeper and more complex technical issues. But, PAG is there and will not leave people on the side. This is the most profitable Company and they want to stay at that level.
They are working on the issue and trying many fixes and it takes time but I am sure solution is almost there. This engine will be bullet proof very soon.

Agree 100%, which is probably why we haven't heard anything yet. They need to be absolutely sure.

I don't think the issue is Porsche finding a solution but rather identifying the problem. We know symptoms but not necessarily the cause, or causes.

Macca, here is another tidbit for you to fine tune your sleuthing skills.
Below is a photo of the cylinder head. It looks like a new one to me. And I know the head has been off because I have also attached a photo of the just the block with the head removed.
On the end of the head casting there is the part no: 9A1.104.111.9R (at least I think the last letter is an R but I am not 100% sure). Now this might not even be a part number but it sure looks like one. Any idea if this is meaningful or not?
Oh, and just to be complete on the camshaft part numbers, the intake camshaft part no has also changed to 9A1.105.276.A1 just like the exhaust camshaft 9A1.105.278.A1
