Frequently Asked Questions
In an interference engine, it can cause the pistons to collide with the valves, leading to severe and expensive engine damage.
Unlike a timing belt, a timing chain often lasts the lifetime of the engine (150,000+ miles) but should be inspected for wear, stretch, or noise during major services.
Chains are generally more durable and less prone to sudden failure but are noisier, heavier, and more expensive to manufacture. Belts are quieter and cheaper but require scheduled replacement.
It is a complex, precision job requiring special tools and knowledge to correctly time the engine. It is generally recommended for professional mechanics.
