The O-ring on the tip of the fuel injector does not cause the fuel injector to fail. The O-ring on the tip of the fuel injector is only an aid during the break-in period of the engine. The O-ring is only needed until a "carbon dam" is built up during break-in. It is normal for this O-ring to be burnt, cut, and damaged after the O-ring has been run in the engine.
