Valve cover gasket leaks are frequent; check for oil seepage and replace gaskets as needed to avoid engine bay contamination. Cooling system faults, such as radiator or thermostat failure, can cause overheating—monitor coolant levels and temperature gauge, flushing the system periodically. Ignition components like spark plugs and coils may degrade; replace spark plugs every 30,000 km for optimal performance.
