What are the precursors of EA888 timing chain failure?

[JoannaMarie]

Here are the precursors of EA888 timing chain failure: 1. During driving, the engine will produce obvious abnormal noises. After tooth skipping occurs, the ignition timing will change, fuel consumption will increase, and power output will significantly decrease. If not replaced in time, it may even directly lead to engine failure. 2. After driving for a certain mileage, the car will experience varying degrees of increased fuel consumption. This is not solely caused by timing chain failure, so a comprehensive inspection is recommended. 3. If it's a normal phenomenon, maintenance is suggested. The decrease in power output is largely caused by the engine and related component configurations. Once the timing chain fails, it will restrict cylinder movement and affect the intake and exhaust functions.
