Porsche 911 991 Bore Score Strikes This Generation

A shocking new story from All Torque magazine reveals a catastrophic case of bore score in a Porsche 991.1 GTS — a model long believed to be immune from the infamous 996/997 engine issues. After just 1,200 miles of ownership, the engine suffered a melted spark plug, a holed exhaust valve and severe cylinder scoring across multiple cylinders. This dramatic breakdown raises an urgent question: does the 991 generation also suffer from bore score?

In this video, we explore the owner’s journey, what caused the failure, whether this is an isolated case or a warning sign for all 991.1 owners, and what this means for anyone thinking of buying one. As a 997 owner myself with over 100k miles and no bore score, this development is deeply concerning. Should all flat-six engines be warmed properly before high revs, or is there something more serious at play? Let’s break down the truth behind this worrying discovery.
