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.
