WHAT DOES A messed up timing chain sound like?
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.
Can a timing chain be adjusted?
The simple answer is No, it is not. Timing chain problems are not uncommon, especially in high-mileage vehicles. Like any other moving mechanical component inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil.
When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
What can I do to avoid timing chain problems?
To avoid timing chain problems you should maintain your engine properly and have the engine oil changed at recommended intervals. Using premium quality engine oils and oil filters will also help. Keeping the proper oil level will ensure that the timing chain is always lubricated.
Can a timing chain be replaced on a pushrod car?
In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.
Why does a timing chain have a tensioner?
It ensures that the piston is close to or at top dead center at the moment of combustion. If a valve is open or the plugs don’t fire at the right time the air and fuel that have entered the combustion chamber are not going to ignite. Most timing chains use a tensioner to keep them tight and to keep them from jumping.
