: If left untreated, a stretched chain can jump teeth, causing the engine's timing to fail and leading to severe internal engine damage. 2. Carbon Buildup on Intake Valves

This typically becomes noticeable between 30,000 and 60,000 miles Timing Chain Wear : If left untreated, a stretched chain can

Regular fuel additives cannot fix this because they never touch the valves. The only permanent solution is physical cleaning, usually via walnut blasting or specialized chemical induction treatments every 50,000 km. Premature Timing Chain Wear and Rattling
