Does My Timing Chain Need to be Replaced?
Does Your Timing Chain Need to be Replaced? That depends. Unlike a Timing Belt, a Timing Chain usually is not recommended to be replaced by mileage. This means that the Timing Chain is not a normal Maintenance Item like a Timing Belt. However, there are several other reasons that a Timing Chain may require service. Some of these can cause other issues in your vehicle as well. The Chain itself can stretch or get damaged. As a chain stretches it allows the timing of your engine to be slightly off. This can cause issues such as Misfire, Low Compression, or the engine not to run at all. A Timing Chain Tensioner can also go bad. If the Chain is not under the proper tension, the same issues as a stretched chain can occur. Below is a picture of the timing chain tensioner holding the chain at the proper tension
