Ticking Noise From the Engine? It Could Be the Timing Chain

What a timing chain does

The timing chain keeps the crankshaft and camshafts turning together, so the valves open and close at the right moment. Unlike a timing belt, it is usually built to last the life of the engine.

Over time the chain can stretch, and the tensioners and guides can wear. That lets the chain rattle against its housing.

Signs to look out for

Watch for these signs:

• A ticking or rattling from the engine, often worse on a cold start
• A noise that fades as the engine warms up, or gets louder under load
• A warning light, or the engine running roughly

Low oil and missed oil changes can make chain wear worse, so keep up with your servicing.

What we found

A customer brought in a car with a large ticking noise from the engine. We checked the engine and confirmed the timing chain was the cause, so the customer had a clear quote before any work started.

Do not ignore a timing chain noise. If the chain jumps or breaks, the engine can be badly damaged. Call us on 01922 682200 and we will check it in Walsall and give you the options before any work starts.
