Will Timing Chain Skipping Teeth Definitely Cause Valve Interference?

[ColinLee]

Timing chain skipping teeth does not necessarily cause valve interference. The methods to determine whether valve interference occurs due to timing chain skipping are: 1. A slight noise is heard when the car is idling; 2. The noise becomes obvious at medium speed; 3. The noise becomes chaotic or disappears at high speed; 4. The noise reappears during sudden acceleration, and in severe cases, the timing gear cover vibrates. Symptoms of timing chain failure include: 1. Abnormal engine noise; 2. Increased fuel consumption; 3. Increased oil consumption; 4. Car fails to start; 5. Insufficient power; 6. Severe exhaust emissions. Timing chain replacement is required under the following circumstances: 1. When it exceeds the recommended service length; 2. When inspection reveals elongation, wear, or breakage of the timing chain; 3. When measurements with a vernier caliper show that the thickness of the chain tensioner or chain damper exceeds the service limit.
