From my understanding, the GT1 Mezger engine does not suffer the same scoring issues found on the M96/7 engines. I don't see scoring to be a widely publicized issue with the subsequent 9A1 engine either. The Mezger engine is widely held to be bullet-proof. Aside from failure of the adhesive used to attach the coolant pipes on the 3.6L Mezger, they are an extremely reliable for an engine that turns 9,000 RPMs.
