991.1 GT3 value after the 10yr engine warranty ends

I had the "unfortunate" opportunity to see inside many of the 991.1 engines, including I was told were the latest. These did have the DLC fingers. None had any new extra oil spray parts fitted. Those would certainly help and out of interest, would love to see how they did it.
Thank you for your input and involvement on this topic.

I find it hard to believe PAG would replace these motors at such numbers and cost without providing a stable remedy. Had thought the G6 solved it all, but this has wildly stirred the pot.

I believe we do not yet have enough (if any) G6 motor failure data to go by, and only know of a few G-series owners who have racked up 20+ K miles thus far.
Same theory follows those F-series (2015+) and some early G-series motors that have yet to go because Porsche did apply DLC coating or who knows what else in attempts to remedy the issue taking those motors longer to let-go.
I would feel much better hearing this news from PAG/PNA themselves to settle it for certain.
Even friends who work for Porsche seem to have signed NDAs as everything is so 'secretive,' and I understand why (sort of).
Perhaps at the 10 year warranty expiration PAG will send current 991.1 GT3 owners a letter of explanation and/or perhaps a nice severance check: yeah right, but wishful thinking!

Bluesclues has piled over 20k on his G6 motor with a ton of track miles. DLC coating the parts didn’t solve the problem, they were still letting go. When you rub two dry pieces of metal together there gonna wear down. Give Porsche some credit for getting to the bottom of the problem and adding the oil sprayers to create a barrier between the metal parts. Neil never said he specifically saw G6 motors that failed. I’m still waiting for someone to pop on here and say ‘my G6 had a top end failure’

You know Neil is in the business of selling rebuilds, right? He designed his engine fix before Porsche decided to give a 10 year extended warrantly, right? The warranty was initiated in, im guessing here, 2016-2017. Neil never has seen a G6 motor as they weren't even designed when he was looking at broken engines. Does that make any sense?
Perhaps I am reading too much into it or missing something?

I just went back to re-read all pages and still leave with the impression that the G6 is still a flawed design.

Have anyone yet dissected a G6 since release to observe damage?
I saw how damaged my E-series motor was, and no way would I had rebuilt that motor provided all the contaminants that went throughout the entire system.
Yes it does. The exact same cylinder head, spray bar location and the exact same finger design and hydraulic actuation. The difference was the coating that gave the surfaces a harder wearing surface. There is not a lot you could have done,(Porsche) other than the band aid they did. The DLC certainly made a difference.
The .2 engine was changed over to solids to get away from the .1 design. It was never for a performance upgrade, although it can add some performance.
In my opinion, someone was asleep at the wheel when the .1 design was Ok'ed.

Not enough testing on the road, Porsche released the engine too soon, and it came back to bite them hard! All these .1's should have a liftetime warranty on these engines, they released a lemon! Run some Good oil, and hope for the best!

I don't mind the warranty being limited as long as the replacement engines actually fix the problem. There's no justification for providing flawed replacement engines, hoping that not many of them will fail before the warranty expires. It would be in Porsche's reputational interest to provide a substantial warranty for these engines (based on miles after the engine is installed, not years).

The perspective is that the .1 design is flawed and even though Porsche made improvements up through the G6, the design is inherently flawed (only fixed by a redesign in the .2). What will be the longevity of the latest G6? Who knows. And I suspect that the Porsche lawyers provided input re the implications of simply improving the .1 design or acknowledging its flaws by replacing the .1 with the .2 design.
