      Injectors are crucial to the efficiency of a diesel engine.  When injectors wear out they will cause catastrophic damage to a diesel engine.  Injector failure can cause damage to the piston(even burn a hole through it in severe cases) by burning metal off of the piston cup.  The metal will then travel throughout the engine and turbo and continue to cause more damage.  Injectors are engineered and are designed to handle extreme pressures(up to 25,000 psi) but at those pressures they are going to fail eventually.  Mileage will begin to suffer, loss of power, excessive black smoke, white or gray smoke are all signs that you might need a new set of injectors.
