What maintenance action is recommended for timing chains?

• A. Regular tightening
• B. Frequent replacement
• C. No regular maintenance is usually needed
• D. Periodic lubrication

Answer: (C)

Timing chains are designed to be durable and typically do not require routine maintenance like tightening or frequent replacements. Unlike timing belts, which may need regular inspection or replacement at specified intervals, timing chains are intended to last for the lifetime of the engine. They are generally made of metal and are more resilient to wear and tear. This answer reflects the engineering of timing chains, which allows them to operate without regular adjustments or maintenance schedules. While it is essential to keep the engine well-maintained and address any oil changes or related issues that can affect the timing chain's function, the chain itself is engineered to be a low-maintenance component under normal operating conditions. Periodic inspection may be advisable if there are symptoms of timing chain issues, but routine maintenance is not typically a necessity for timing chains.
