Timing chain

There is no manufacturer specified replacement interval for the engine timing chain on Hyundai i20 2014 1.1 diesel, expecting it to last until the engine is overhauled.
Based on real life experience, the Hyundai i20 2014 1.1 CRDi timing chain change interval is approximately 100,000 km as at this mileage it may become overstretched and require replacement, so it is recommended to check the condition of the chain periodically after this mileage is reached and replace the timing chain if it becomes excessively stretched or if unusual engine noises occur.
