2-valve Regenerative Repair System 

The built in autonomous self-repair system that exists inside the motor of a 2-valve 4.6L DOHC Ford V8 motor.

I hit a puddle and water got into my motor, causing an engine tick and a triple misfire, but after a week or two, the 2-valve Regenerative Repair System kicked in and the tick is gone and all 8 cylinders are firing normally.
