I do own a 991 GT3 and I do like to read these posts on Pistonheads, but l get fed up of all the negative b
hing attitude that some people on these forums seem to create hence the reply to help the genuine owners of this model (This doesn't happen on rennlist)
Having read this post yesterday I phoned Porsche who informed me that there are 35 cars that are effected mine was not one of them as mine is a later 2015 model
The smoke issue that I have read about many times and l have asked Porsche about and they told me this is normal.
It used to happen on every start up and then it use to be every other start up or longer intervals.
It seems have stopped all together now that I have covered 4,500 miles and I have never had the need to top oil up from new which I was surprised at considering the clouds of blue smoke on start ups. Hope this helps current owners of this model.
The only time my Cayman R ever smoked on start-up was when I had to park the car with the tail down a steep gradient --- outside the hotel we were staying at for the Spa days. I must say that it worried me for a moment --- but it does highlight the fact that all cars can do it and it's no more than one of those things. The car has now done over 34000 miles and only used any appreciable amount of oil in the first 1000 miles (350ml I believe !!)hing attitude that some people on these forums seem to create hence the reply to help the genuine owners of this model (This doesn't happen on rennlist) Having read this post yesterday I phoned Porsche who informed me that there are 35 cars that are effected mine was not one of them as mine is a later 2015 model

Engineering and software development are completely different when it comes to risk and impact analysis (unless the software is in control of someone's life)
Do you honestly think an engineer will build a bridge over a river and say "we reckon it will work and if it starts to crack and a couple of cars fall off then we will add some more steel or redesign it later"
That sort of thinking is borne from budgetary constraints and a need to release the product to the public as soon as possible.
Your clearly not an engineer. i am and for many years so I dont honestly think I honestly know. Do you seriously think that aircraft dont have a few cracks and we think add some bits later I can tell you as an ex aircraft engineer thats exactly what happens. Tacoma bridge remember that. Software impact totally different for risk analysis- really if you designing games maybe. Go and ask someone in the nuclear processing industry about protective function.

What a bunch of negos!!!! 
May I ask if anybody who has posted a negative comment above owns or has owned a 991 GT3 or has at least driven one?
My guess is no.
I assume that you have directed this at me and I am happy to confirm that I havent driven one.May I ask if anybody who has posted a negative comment above owns or has owned a 991 GT3 or has at least driven one?
My guess is no.
Does this make you happy in some way or prove that the engine is in fact a masterpiece of reliability?

How many actual failures have there been?
I dont know, only Porsche knows. Of course, they reacted reasonably quickly to the first failures, and rightly so.As you know, all engines were changed and yet there were more problems and some are now on their 3rd engine.
And now we have this new recall. Whats behind it, who knows, but it just proves that this engine has had a very troubled birth. You owners seem to be testing it for them.
Porsche released this engine as the 'motorsport engine' in 2013 and in 2016, they will be racing the Mezger. With the move towards smaller power units with motorised and turbo assistance, I dont see it ever racing.
I have no doubt that its a glorious engine in terms of its power delivery, but can you really see it doing a 6 figure mileage without issue?

Sorry, just read back my post and it does come across as rather blunt and curt, I apologise if I caused offence.I'm just disappointed that Porsche have released another engine that has so many problems. There used to be a time when Porsche engines were bulletproof but since the M96 engine and now these issues, its no longer the case.
For a brand new 991 GT3 owner, these issues and recalls are all fun and games with no chance of any of you being left with a car that is 'uneconomical' to fix but what happens a few years down the line when the warranty runs out and the desire by Porsche to fix these issues dries up?

You reckon bulletproof? Blimey chain tensioners, the 2.7, 964? Porsche seem to have built as many bad as good engines over the years I'm just disappointed that Porsche have released another engine that has so many problems.

Plenty of well-publicised issues with the old Mezger engine which are conveniently ignored by those keen to dismiss the new engine!
Could you post a link please? I can't find any issues with the old engine. Did Porsche have to recall earlier iterations of the gt3 as well?Patent said:

No RMS issues, no Conrod issues, no engine block issues?No RS 4.0 cars with replacement engines?
Really?

I didn't forget.
If you want to find out for yourself, I'm sure you can manage to search on here, on Rennlist etc etc
Are you saying you've tried to search and not found anything?If you want to find out for yourself, I'm sure you can manage to search on here, on Rennlist etc etc
It seems more accurate to say that you've forgotten to look...!!

Had a look but honestly I can't find anything - I do remember something about the 4.0rs but not sure exactly what that was about.

When you get home, Google 'Mezger', 'conrods', 'porous', 'RMS', 'RS 4.0' and you'll probably find the same links as I did!Had a look but honestly I can't find anything - I do remember something about the 4.0rs but not sure exactly what that was about.
