Are you having issues with your N12 & N16 – ONE & Cooper Non-Turbo Engine
- Timing Chain Wear: Less common than N14, but still an issue—can trigger VANOS-related fault codes. Regular inspection is recommended.
- VANOS Faults: Often caused by faulty solenoids, low oil pressure, timing chain wear, or sensor failures.
- Valve Cover & Oil Leaks: Common around the valve cover gasket and oil filter housing.
- Thermostat Housing & Water Pump Leaks: Common coolant leaks that require prompt repairs to prevent overheating.
- Dropped Valve Seats: Overheating can cause valve seats to drop, resulting in severe engine damage. Keeping the cooling system in top condition is essential.
- Oil Consumption & Blue Smoke: Usually caused by worn valve stem oil seals or excessive bore wear.
