Disadvantages of the Mini N14B16C engine
Overheating is the motor’s primary issue, and cylinder head cracks are frequently seen here;
Large oil consumption follows, which causes coking in the intake;
Less than 50,000 kilometers are frequently covered by an unreliable timing chain, particularly its tensioner;
A small resource includes a high-pressure fuel pump for the injection system, a vacuum pump, and a phase regulator;
A thermostat and a water pump are also weak points of this power unit.
