Iron liners can score, because it has happened since day 1 of the internal combustion engine. The question is, are later M278s (or even M157s) somehow, fundamentally, better and longer lasting? Do we really have data on this? We know early timing chain systems are problematic, sure. But that's only the start of the potential list of issues.

Indeed, scoring marks does occur even in the factory, but the real issue arises when the piston rings exceed their wear limits and malfunction. In such instances, since the engine must be removed, it would be logical to rebuild it with superior racing components.
