Disadvantages of the Renault N7U engine
Oil leakage from the oil separator is this motor’s most well-known issue;
Additionally, a respectable oil consumption may manifest as a result of clogged crankcase ventilation;
Avoid letting the power unit overheat because the gasket breaks through here very quickly; replace the timing belt more frequently than the recommended 120,000 kilometers because when it breaks, the valves bend;
The engine’s supports, pump, thermostat, and fuel pump are additional weak points.
