Common Weaknesses & Maintenance Notes

Despite its strengths, the N20B20 engine is not without weaknesses. Common issues reported include timing chain tensioner failures, particularly in earlier versions, which can lead to chain stretch or rattle. Oil leaks from the valve cover gasket and high-pressure fuel pump wear can also occur over time. Turbocharger wastegate rattle and coolant system leaks are additional areas that require attention. However, regular oil changes using high-quality synthetic oils, timely timing chain replacement, and proper cooling system maintenance can prevent most of these problems and ensure long engine life.
