I don't think it's scaremongering but bore scoring is only one of the elements that affect Porsche engines of that generation. The most concerning is IMS bearing failure which resulted in legal action being brought against Porsche in the USA.

Here's a summary of the IMS bearing problem, many others are available.

And here's a summary of the potential engine problems that can beset that generation of engine. Hartech are highly respected Porsche engine specialists and have done a lot of research into these problems.

The turbo engines of that generation are a different case and don't suffer from the same problems.

Proven modifications are available for the IMS bearing and it's something I'd do immediately after buying a car.
