Bore scoring on a 997 turbo S
Discussion
The Article said:
" I was initially concerned about some scoring on the engine cylinder bores, and took some photographs with the aid of a bore scope and sent a copy to Porsche Technical. I've been assured by everyone that all is well. The car doesn't smoke excessively and uses no oil to speak of, so I'm trying hard to suppress my paranoia and enjoy the ownership experience".
Without doing Clive White an injustice, as I don't know him, It sounds like paranoia. I mean I wouldn't take a boroscope of a healthy engine, unless there were real symptoms I was concerned about. Also PCGB Tech have given it the all clear.
No need for tinfoil hats, or conspiracy theories, Its claims like this that cause them to be needed in the first place.

There will always be some marking on the bores of an engine in the direction of piston travel. The surface finish of new rings/bores is never perfect so there's always a period of 'bedding-in'. The high spots on the new bore walls or rings will lead to what I like to term 'polishing lines' up and down the bore as the bedding-in process takes place. These are totally different to the deep score marks caused by breakdown of the oil film and susbsequent seizure of the piston to the bore wall."

I read the article in PP - seems he is very pleased with his Turbo S and plans to keep it long term.
Presumably he has access to a borescope and, as he does a bit of motorsports in it, perhaps he had a look out of interest. Borescopes are widely employed in many industries, especially aviation where they are routinely used to check engine/turbine condition.

It must be said, you've got to wonder why someone would boroscope such a new engine as he doesn't say what prompted him to do so 
Exactly this. I wondered the same, especially as he says after that it was running fine with no issues.A boroscope can be bought inexpensively - cheapest I've seen was Aldi @ £50. Costco have them now for well under £100.
You only need it to save you a few hours and a lot of skin off your knuckles to make it worhwhile owning one - at least that's what I'm hoping when I actually find a use for mine...
