The timing chain is an important part of many combustion engines and ensures optimal interaction between the mechanical engine parts. It is located next to the cylinders in the engine, where it is inserted into the gear rims of the camshafts and connects the crankshaft with the two camshafts that control the valves of the engine.
Repairs & Replacements
Timing Chain
When should I replace my Timing Chain?
A timing chain is made of metal, similar to a bicycle chain. A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing chain typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle.
Signs of timing chain problems
- Rough idle - A worn timing chain introduces slack into the connection between the camshaft and the crankshaft.
- Poor Performance - A worn timing chain may cause the cylinders to be unable to fully fill with a fuel and air mixture.
- Abrupt Performance Change - A timing chain that receives sudden damage or extreme wear due to overheating or lack of oil.
- Clattering Noise - A clattering noise coming from the front of the engine can be caused by a loose timing chain.
Common Questions
Timing Chain FAQ
What does a timing chain do?
The timing chain keeps the camshaft and crankshaft in sync so your engine runs correctly. If it stretches or snaps, the engine can suffer serious internal damage. Unlike a cam belt, timing chains are designed to last the life of the engine, but they can still wear and cause problems.
What are the signs of a worn timing chain?
Common signs include a rattling noise from the engine on startup, particularly when cold, a warning light for variable valve timing, or poor engine performance. If you notice any of these, get it checked as soon as possible.
How urgent is a timing chain repair?
Very. A worn or loose timing chain can snap without warning and cause catastrophic engine damage. If you're hearing a rattle from the engine bay, don't leave it. Book it in and we'll assess it for you.
Does a timing chain need regular replacement like a cam belt?
Timing chains don't have a set replacement interval the way cam belts do. However, using good quality engine oil and keeping on top of servicing helps them last. If yours is showing signs of wear, we'll advise you on the best course of action.
