The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles. If driving an older vehicle, or one with close to 100,000 miles, it is recommended to look for symptoms of the timing chain going bad or failing.
Since the timing chain can go bad and will need to be replaced, it is important to be able to recognize the symptoms and have it repaired before it fails completely.
Signs a timing chain needs to be replaced include:
Later model VVT applications will generate engine codes and check engine lights prior to engine rattle
Older, pre-VVT applications will generate engine rattle
What causes timing chain noise?
Timing chain noise is commonly most noticeable during cold startup of the vehicle when oil pressure and oil flow is at its lowest. Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover. If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.
