While timing chains are more durable, they do have their drawbacks. They tend to be heavier, which can increase the overall weight of the engine. Additionally, timing chains can be noisier than belts, leading to some engine noise which may be undesirable for certain drivers. They also require regular maintenance, as they need to be properly lubricated, and if they become loose over time, they can affect engine performance and lead to premature wear.
