Disadvantages of the Renault N7Q engine

  • Most often, Renault owners with such an engine are worried about grease leaks from the oil separator;
  • Due to clogged crankcase ventilation, an impressive oil consumption often appears;
  • The timing belt does not always serve the required 90,000 km, and when it breaks, the valves bend;
  • This power unit is afraid of overheating and the gasket breaks through here very quickly;
  • Weaknesses also include engine mounts, thermostat, pump and fuel pump.
