..P, FYI, no, there really isn't a way to do it in the car, which is unfortunate. You need a sunnen machine to do it correctly.

If you are close to a Porsche dealer, they can or should be able to refer you to a shop that can re-hone the cylinder. If it isn't too deep, they may be able to "buff" it out with the silicium paste. Otherwise, you will be looking at a oversized piston and rings. Fortunately, you only have to change the one that is bad.

Is it possible to rebore these cylinders? I was under the impression the bores are specially treated for long life but can't be rebored.
