A stretched or rattling timing chain can cause engine warning lights, rough running and ultimately engine failure. Pam's MOT Centre diagnoses and replaces timing chains in Bletchley and across Milton Keynes.
A timing chain performs the same function as a timing belt — synchronising the crankshaft and camshaft — but is made of metal rather than rubber. Most manufacturers design timing chains to last the life of the engine, but they can stretch, wear or fail, particularly in higher-mileage vehicles or when oil changes are neglected.
If you notice any of these signs, have the vehicle inspected promptly. Continuing to drive with a failing timing chain risks serious engine damage.
Timing chain replacement is a major repair that requires removal of significant engine components. Our mechanics have the experience and equipment to carry out timing chain replacement accurately. We fit quality components and take care to set the cam timing precisely before reassembly.
Not all vehicles have a timing chain — some use a timing belt that requires periodic replacement. If you are unsure which system your car uses, we can advise. For comparison, see our page on timing belt replacement in Bletchley.
Unlike timing belts, timing chains do not have a fixed replacement interval. However, they should be inspected if you notice rattle on cold start, engine warning lights or timing-related fault codes. Neglected oil changes are the most common cause of early timing chain wear.
Timing chain replacement is a labour-intensive job and costs vary significantly by make and model. Call us on 01908 644 514 for a quote for your specific vehicle. We will provide a full breakdown before any work begins.
Depending on the vehicle, timing chain replacement typically takes one to two days. We will advise you on the specific time when you book.
We advise against it. A rattle on cold start is an early warning sign — continuing to drive risks the chain jumping or breaking, which can cause catastrophic engine damage. Book an inspection as soon as possible.
Depending on the condition of the system, the timing chain tensioner, chain guides and sprockets may also need replacing. Inadequate oil pressure is a common cause of timing chain wear, so we check for oil pressure and lubrication issues during the replacement process and advise on any further work needed.
