Porsche give 10 year 120k warranty on exploding GT3 engines
Discussion
Taken from Rennlist in respect of the seemingly pretty common cam follower issues resulting in a pretty much standard or 2 engine replacements on the 991
Official Announcement from Porsche
"Porsche will extend the warranty on the engine of all 991.1 generation GT3 vehicles in all markets with respect to failure modes related to this issue. The extension will provide coverage for 10 years from the original in-service date, or 120,000 total vehicle miles, whichever occurs first. (The base bumper-to-bumper warranty remains unchanged at 4 years or 50,000 miles for the US, as do all other warranty terms and conditions.) The warranty extension is fully transferable to any future owner. All US owners will be informed in writing and the change will be applied and processed with no additional owner action required. If a vehicle shows the described failure patterns (e.g., misfire at high revs and check engine light) and the inspection in the workshop shows the failure patterns, Porsche will replace the defective engine with a new engine having the latest parts. Porsche confirms that the issue is isolated to the 991.1 GT3, and that the 991.1 GT3 RS and the 991 R are not affected."
Very glad about this had set my heart one one involving selling off a couple of properly nice cars to make financial room but I was worried about the affect granading engines would have post warranty. This would seem to me to be a big confidence booster. Just hope the 991.1 doesnt go up off the back of this!

Value of 991.1 GT3 suddenly increased by £15k ?!Official Announcement from Porsche

So ideally, I was my engine to go bang now so that I can get the new engine (although of course my car is already under warranty and would be whilst it is under my ownership).
Should support second hand values once these cars get to 4,5 6 years old though?!

Is this 10 year warranty in the US only or does it also apply to UK cars?
I'm not sure why it would apply to US only.Didn't the US porsche owners put together a class action lawsuit against Porsche regarding the IMS issue on M96/97 engines? I believe they won a settlement too.

If you are looking for a 991.GT3 grab one now!!!!
When the new 991.2 GT3 starts appearing on the used market I reckon it will be about £160-£180k. This makes the current one at around £130k a bargain!

That's actually not a daft comment. Watch the PTS JZM car sell now - with the rumoured huge PTS price hike and the now 10yr transferable warranty things have just got much better for the flammable .1
This is my car your talking about. So should i sell it for more now...mmmm i wonderDurzel said:
Interesting that they do this, but no formal acknowledgement of bore scoring on their older "cheap" cars.
^ this. Guess the benefits of good press and perception of taking care of the GT cars outweighs the cost of the new engines as ultimately it's 4-5k cars at most that might have that issue and a good % of them probably won't show it while the far greater numbers of M96/97 engines sold meant the costs were far greater. Good news for the .1 gt3s though.
It's no surprise there are many reasons why Porsche would do this and below is one of them as they are not expecting a fast amount of engines to be replaced out of the total production so this is why they feel confident to offer the extra warranty. Even if they have to replace more than anticipate it's positive move for the Porsche & their customers in providing confidence in there products plus more sales in the future.
warranty extended to 10 years/120,000 miles with respect to failures related to this specific issue (from in-service date)
- Warranty extension is fully transferrable – Covers all current and future 991.1 GT3 owners with no action required by the owner
- If an engine fails as a result of this issue the defective engine will be replaced with a new engine that has the revised parts (no more top end rebuilds)
- Includes all markets (this is global, not just for US owners)
Second Presentation: Understanding The Issue
Dr. Walliser ran this presentation. He explained the cause of the finger follower wear issue, and the steps Porsche has taken to resolve it. Without getting into a great amount of detail, which we are unqualified to do, the issue is caused by a metallurgy defect (inclusion) close to the surface of the finger follower. Most finger followers do not have these inclusions, or they are not close enough to the surface to cause increased finger follower wear. This explains why the vast majority of 991.1 GT3's do not, and most likely will never experience this problem.

Can anyone give me an idiots guide to a "finger follower" please - what is it and what's it do ? Thanks warranty extended to 10 years/120,000 miles with respect to failures related to this specific issue (from in-service date)

FFS, must I do EVERYTHING for you ?? 
Have a read of this from page one :
https://rennlist.com/forums/991-gt3-gt3rs-and-911r...
When you get to page five, you'll see these two images (and don't just go straight to page five you horrible little man you ('cause they'll be a test once you report back to say "I get it") Do I make myself clear ?
1. Is the cam lobe (round whirly thing with bumps on it that pushes on the cam follower (2) (or finger) f*cking Yanks ....
2 Cam follower, does what is says on the tin, follows the cam and transfers it's bumpy motion onto the end of the valve stem to open and close it.
These look to have some wear on the "pad" that bears on the cam lobe. The pad is given a DLC or Diamond Like Coating that should be very hard wearing, it should be black as can be seen on the pad on follower A. However on follower B the black has gone (worn away) and the base metal beneath is wearing and scuffed. Eventually the cam will wear and not provide the correct amount of lift, but in doing so will deposit lots of fine metallic particles into the inside of the engine, this ultimately ends up in the oil, and metallic particles in your oil, don't allow it to lubricate as intended.....
The failure of the DLC can be down to two issues : Insufficient lubricant of what is very high load/high friction interaction between two metallic parts, or poor surface coating.
3. Hydraulic tappet (or if you like McDonalds, think Trump should be president and think drinking a gallon of Pepsi with your breakfast is in any way acceptable, you'll call it a lifter) Relies on oil pressure (generated by the engine) to allow the valve clearances to vary as the engine heats up. Has no place in an engine that revs to 9000 rpm, but cuts down down on maintenance bills by removing the need for routine valve clearance checks and adjustment.
Don't say I don't ever do anything for you
