Thanks for taking the initiative and helping all of us - I will definitely drive mine with more confidence and purchase my next Porsche knowing that they care about their long term customers and not just short term profits!

Great job, guys! Glad to hear they do not believe the problem issue is present on RS's and R's.

Great job guys!! RS as predicted has zero issues as it was basis for GT3R and issue had been fixed by then! What a great company Porsche is!!

Great job to all . Porsche is the greatest . I am glad they understood the GT owners are behind them and they will continue to build GT cars for us to enjoy.

Fantastic effort guys, and also really speaks to Porsche's commitment to its GT buyers. Way to truly handle the situation on both sides.

Bravo.

Very nice guys, and "kudos" to you all for providing relief for 991.1 GT3 owners. What's fantastic this should get rid of the need to sell the .1's with a storied history. Hell 120k, and 10 years is fantastic. Diplomacy always works with a good company, and Porsche prides themselves on quality. They have a consulting division, and if you have not heard about them look it up. They focus on brand and quality and customer service. There ya go you all experience all of it down south in the land of hospilaty.

It's very clear Porsche knew about this issue and was dealing with it internally much earlier, but do you think they were planning to come forward with this deal to all the .1 gt3 owners eventually?

Nicely executed on Porsche's part. Very refreshing to have a company stand behind its products whether it's a GT car or Panamera.

Going into detail on the issue and clarifying the engine versions was very respectful too.

I guess, drive with confidence!

Rob and other member of COG that contributed to this endeavor, thank you very much.

I do have a question:
When PAG indicated that this did not affect the RS or the R were they referring to the G engine or car specific? We know that the G engine has had no documented finger follower failures, but certain things changed after it was introduced. I believe the SN # around 5400 changed other valve train components.

Dr Walliser stated the R has the new specification followers. The RS has not seen this problem due to fact it requires having the inclusion near the surface but also a complex set of factors that add to the forces, oil film and heat applied between the two surfaces that don't seem to happen in the RS. Remember the RS revs lower so the valve springs are lower value reducing force and stress.

The G engine GT3's may eventually exhibit this issue, while in hundreds of hours of testing, Porsche has been unable to get an RS or R motor to fail. We also have no documented failures of an R or an RS on RL.

The R has a revised camshaft and revised followers (similar to what will be featured in the replacement engines when someone gets one) and the RS has a lower spring rate on the valve springs which lowers the friction.

Well done!

I was skeptical - not of your persuasiveness, but of the monolithic might of Porsche AG being sensitive to this community.
