Defective injectors can cause severe engine knock, the noise is very reminiscent of the failed main bearing. When such a failure, allow engine to idle and consistently to unscrew the union nuts fuel line to the injectors. If, after unscrewing a nut knocking disappears, then the injector is defective.
Faulty injector can also determine if the unscrew the union nuts of pipelines (series) while the engine at high idle. If the engine speed after unscrewing a nut does not change, then the faulty injector. Nozzles checked by a special gauge to the service station.
