Excessive timing chain noise, a rattling or ticking, on higher mileage cars may lead to timing chain failure, which can cause engine damage. There are upgraded chain tension guides with a steel backing to improve durability and a modified repair procedure no longer requires the removal of the cylinder head to replace the timing chain. Maintaining proper engine oil level and frequent oil changes are important to ensure the long-term durability of this engine.
