How to Determine if the Timing Chain is Stretched?

[EmeryFitz]

It is impossible to determine if the timing chain is stretched by yourself, but a 4S dealership can read the crankshaft sensor and camshaft sensor. If there is an alarm indicating operational delay, it may indicate a potential issue with the timing chain stretching. The timing chain works by connecting the sprockets of components such as the crankshaft and camshaft with a high-strength metal chain, ensuring synchronized operation. Due to the high-speed movement between metal parts, wear is rapid and temperatures are high, necessitating the design of an appropriate lubrication system for cooling and lubrication. Additionally, the use of timing chains in engine design also presents the issue of friction noise between metal parts. To address this, manufacturers must take various measures, such as designing optimized chains.
