Defective nozzle unscrewed in turn, weakening the union nuts on high-pressure pipes, while the engine is running at idle speed fast. If the engine speed after loosening nut remains constant, this indicates a malfunction nozzle. Shop can check the injected fuel jet and the pressure of the injection nozzle in the range of 100 to 125 bar and, if necessary to make adjustment by changing shims. The first signs of the appearance of faults in the nozzle: - Misfiring;
- Knocking in one or more cylinders;
- Engine overheating;
- Loss of engine power;
- Excessively strong thick black smoke in the exhaust gases;
- High fuel consumption;
- Enhanced blue smoke when starting a cold engine Withdrawal 2.0l High pressure fuel pump (pump injector) (2.0 liter engine) | r8a. Bolt and washer or nespadayuschim stop member
