Disadvantages of the Renault N7U engine
- The most famous problem with this motor is oil leakage from the oil separator;
- Also, due to clogged crankcase ventilation, a decent oil consumption may appear;
- Change the timing belt more often than the prescribed 120,000 km, since when it breaks, the valves bend;
- Do not allow the power unit to overheat, the gasket breaks through here very quickly;
- Other weak points of the engine include its supports, pump, thermostat and fuel pump.
