There is a rattling sound. A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.Mar 17, 2021
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
For most cars, a timing chain replacement costs between $413 and $1040, or you can order the parts themselves for $88 and $245. It is a tricky repair though, so unless you’re particularly skilled it’s usually best left to a mechanic.
Ticking or clicking noises in the engine.
When the timing belt wears out, it can cause a ticking or clicking sound to emanate from the engine. … If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break.
A timing chain can break with either too much or not enough tension. If the chain does not have enough tension, it can develop slack. This can result in the chain “slapping,” leading to premature fatigue. A chain with too much tension can also fail, as it is placed under excessive stress.
Unless there is a specific problem, the timing chain normally needs to be replaced between 80,000 and 120,000 miles. If you drive an older vehicle, or one close to 100,000 miles, you should have it replaced or at least become aware of the symptoms of a failing timing chain.
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.
It depends on the model, but generally the job takes three-five hours. Costs can increase considerably, sometimes up to $700 or more, if the timing chain breaks before being replaced.
Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley. If the bearings in the pulley are beginning to fail, they will make noise. Eventually, they’ll seize and the water pump will no longer operate, causing your engine to overheat.
The timing chain in an internal combustion engine connects the crankshaft and camshaft. … An internal combustion engine will not run with a broken timing chain or belt. Timing chains are rarely known to break during an engine’s typical lifetime.
It is unusual for a timing chain to snap – they usually stretch/wear over time and become noisy. Timing belts on the other hand can snap if excessively worn as a result of not being renewed at the recommended time/mileage interval.
Can you tighten a timing chain? Timing chain’s have no tensioner, are made to fit, and cannot be tightened. When a timing chain is stretched too far, you purchase a timing set (chain with matching crankshaft & cam gears, as they MUST be changed together. Many engines that run chains have a hydraulic tensioner.

Every car has a timing chain. It is the connection between the camshaft and the crankshaft. … And just like any other car parts, changing a timing chain is required. But you can do the job all by yourself if you have the right tools, some mechanical know-how, and a service manual.
Another very common symptom of bent engine valves is a knocking or ticking noise coming from the engine. … Worn lifters usually make a ticking noise as opposed to a knocking or clicking sound when the engine is running.
Changing a timing chain is not outright difficult but is considered a complex job due to the large number of steps involved. … The timing chain and water pump are both labor-intensive jobs in the same area of the engine, so knocking out both now can prevent having to do many of the same steps again later.
A normal engine has a consistent and smooth sound that means everything is running well. When you hear a rattle or unusual sound, it means that there is a problem with the engine. When the timing chain is loose, it can cause a vibration in the motor resulting in a rattling noise as the engine idles or when starting.
if you hear a pinging or rattling sound when accelerating, low-octane fuel could be the cause. pinging (also called pre-ignition or detonation) can also be the result of carbon deposits, a bad knock sensor, overheating or incorrect ignition timing.
on a regular normal basis, the engine has a constant continuous passive rattling sound from when you start it up to when you turn it off, no matter cold, hot, warm or cool. This rattling sound does not sound overly loud – like the cold start ones. But loud enough to raise an eyebrow.
All Mini Cooper (Cooper, Cooper Clubman, Cooper Paceman & Cooper Countryman) engines have a timing chain and are interference. … Check the belt or chain for other makes and models here.
It’s probably not immediately “dangerous” to drive with an elongated chain, but if it gets elongated enough, it will lose tension, start to “slap”, and may break the plastic cam chain guides or jump a tooth on one of the sprockets, which may cause catastrophic engine damage.
