Gen2 997 - bore scoring
Discussion
Hi all
Does anyone know if the Gen 2 997 suffers from bore scoring?
I'm assuming the IMS problem has gone due to a change in design.
I've seen a nice Gen2 Targa 4S for sale but for the same money I could get a Turbo and not worry about those problems. Problem is that I like the glass roof.

There is a least one case detailed in a thread on here - do a search and it should turn up.

One of mine needed a new engine and another guy on here as Flashgordon seemed to be going through the same process.
The failure itself didn't match up the Gen 1 problems and it is nowhere near as widespread. It would be foolish to try to explain the cause, but we may find out eventually when Indies start fixing them.
If you want a 997 then I'd still suggest Gen 2. It's a great car and the vast majority don't have engine problems.

Gen2 is vastly improved. But if neglected or abused then I'm sure they an still suffer.
+1 but no proven cases to date due to poor design/cooling(but early 2.9 engines did have issues with pistons/rings).yes there has been a couple of random failures and borescoring has been mentioned but the most recent case turns out to be something else.but that is not to say as the engines approach high mileage it wont happen,the cayenne apparently shares same bore coating and their has been talk of bore scoring on 100k+ miles.just make sure the oil is changed more regular than manufacturers 2year 20k miles which is madness imho on a 300+bhp engine.
don't assume you are safe buying a mezger turbo there has also been a few random failures and post 2008 cars use the dfi lump.
for piece of mind just get the warranty and keep it going

Of the two gen2 ''bore scoring' incidents, mine turned out to be a misaligned piston ring. They replaced the linings and the pistons with 991 spec.
There was no scoring of note, but as a precaution porsche GmbH authorised that, so after almost a month of enjoying brand new caymans I got mine back, good as new, possibly better.
I wouldn't think twice about buying another cared for gen2 and will keep mine indefinitely BUT I wouldn't buy without a warranty; it more than paid for itself in the first few months of ownership both in repairs and awesome courtesy cars.
The other incident magic919' was confirmed bore scoring but as to the cause who knows, sometimes stuff happens and his is the only other gen2 I've read about.

Sadly this paragraph says a lot about the modern Porsche. . .
My other car is a bmw 123d and within a year of ownership I had the renowned DMF/clutch issue and the whole lot replaced under warranty, again, the warranty paid for itself.
Maybe I'm unlucky but maintaining the warranty for me, irrespective of brand (BMW, Audi and Porsche) although expensive, has been cheaper than not. Maybe it's just German cars?!

I am glad your issue was resolved and you are back on the road and all those persons who slagged me off on the other post are eating humble pie!There was no scoring of note, but as a precaution porsche GmbH authorised that, so after almost a month of enjoying brand new caymans I got mine back, good as new, possibly better.

I can only give you a vague ''I think so'.
It's what I was told, directive was from Germany, they took a big interest in this one from the initial diagnosis. I'm not sure the 991 dfi engine is all that different though.
I can ask, but by that time I was keen to get back in my car so didn't bother digging too deeply. Initial I went to see the car stripped down, daily updates etc but was abroad when the final work order was instructed and completed.

so it does make me wonder were there discreet improvements over the model years to the bores/rings etc.. and why like my spyder and some late production model 997.2s they introduced a 2012(C) model year for an unknown reason?it does make me wonder especially as they fitted your car with the 991 liner/rings which the 991 also started out as a 2012(C) model year!!!!!!
when my car goes for a service I will certainly ask the question because there will be a difference in part numbers ie 2011 vs 2012 model years

Whole thing is t'internet scaremongering, how many 996's and 997's have been sold vs problem cars? Imho you'd need to be very unlucky to get caught out. Drive them and enjoy them ffs.If you want a 997 then I'd still suggest Gen 2. It's a great car and the vast majority don't have engine problems.

Agreed. I'd say the DFI engine is proving itself to be as reliable as the Mezger units, so far, for driving around on the road
Corrected. Or have I misinterpreted your comment, and you were meaning more that the DFI hasn't been proven on track in any great numbers yet, referring to the 991 GT3 and the future of that engine?

Interesting, has there been many DFI units fail on track then? Must admit I don't tend to keep up with stuff like that, is there an inherent weakness for track work? I've only had mine out the once, so would be very interested to know if there was something else there.

neither, i just felt that your opinion regarding the reliability of the new engines needed tempered slightly by making it a bit more specific. i wasnt making or trying to imply anything beyond that.Or have I misinterpreted your comment, and you were meaning more that the DFI hasn't been proven on track in any great numbers yet, referring to the 991 GT3 and the future of that engine?
