Wow, I was expecting the whole engine issue to be restricted to the 996, but it looks like the 997 is also not immune.
As a Porsche fan, I'm a little sad to hear that.
I saw a Panamera engine at an OPC last year with similar scoring. Ran my fingers inside the cylinder and it was very rough. That said it was 1 year old and dealt with under warranty so no love lost.. As a Porsche fan, I'm a little sad to hear that.

Impreza engine isn't exactly bulletproof - yours may have survived in your ownership, but there are a some well known failure modes for that engine.
The only Subaru engine that had the major engine failures, in 25 years of production, was the EJ25, which was the 2.5 litre lump, fitted to cars after 2005. This is well documented and known amongst the fraternity. The Subaru community are well aware of this engine and its poor build in relation to its Piston ringland failures.A third is a vast proportion, but until Portiacraft post that on here I will take it with a pinch of salt. Saying you learned something from someone who was told by a third party is standard PH fare. What we need here are more facts, and less hearsay.
Edited to add: and while the 2.5 has been the main issue for Subaru, it's not the only one. Plenty on the net about head gasket and big end issues. But I agree, still seemingly much more reliable than our engines - sadly.

Can anyone tell me if the Gen 2 Cayman 2.9 is liable to this? We have one in the family, but still under dealer warranty for now.
I wanted and nearly bought a 997 last year. These worries put me off so I bought an Aston Vantage instead. You know it's bad when you buy a hand made British car over a German one for reasons of reliability.
We can't pretend the Porsche engine failures are allowable under the pretence that 'all cars have inherent problems'. Just try finding Aston Vantages with replacement engines, compared to Porsches. Even with their lower sales volumes, the maths doesn't add up. The Aston should not be more dependable than a Porsche, but it is. But then again, maybe that's because the man behind the Aston was the man behind the last of the air cooled, Porsche 993 .
On the other side to this, I still think that if you want a car, you should just take the risk. Life's too short. They're great cars. I would still consider a 997 and simply cross my fingers.

Indications seem to be that they don't suffer from bore scoring to any extent. I believe a small number of cases have been reported, but they are miniscule in comparison.Kawasicki said:

Hmmmmmmmm,As a Porsche fan, I'm a little sad to hear that.
997 2004><2009
996 1997><2005
964 1989><1994
2.7 1974><1978
Shouldn't be suprised really. Porsche have had a few duffers over the years.
So the 997 hit the showrooms with major design / component quality issues
Which resulted in
1) Bore scoring
2) IMS failures
3) And a 'dodgy' gearbox relating to selecting second gear
Being a newcomer are the turbo cars generally more reliable?
I am astonished at the number of horror stories owners have posted

BMW, swirl flaps being injested by the engine, engine needing a re build
There has been numerous cases of total engine failure in the BMW 1-Series, 3-Series and 5-Series vehicles built between 2007 and 2009. The cause of which have been because the timing chains have snapped.
VW, despite best efforts the engine used from mk4 golf onwards suffers from pre ignition, for which there is no cure
Subaru, uk STi's hatch back lunching engines? Very common, can't drive a classic shape Impreza at high speed for prolonged periods as the air flow will miss the scoop causing over heating and ultimately engine failure
I've had all the above.
Cars break, fact. It doesn't matter what it is. Nothing is truly bullet proof.

I've come to this marque from the likes of BMW, VW and Subaru and really expected a much higher level of engine reliability. Having to fit all these aftermarket gizmos to protect the fragile engine is piss poor on the manufacturer part. I think they flopped with the 997..
