What do you do when your timing chain rattles?
Don an automotive stethoscope and place the probe on the top or side of the timing chain cover. If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.
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.
Can a bad timing chain cause an engine to fail?
3. Engine won’t start or fails. 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.
Is the timing chain on an engine made of metal?
In order for your engine to fire, the timing chain must smoothly rotate around the gears without hesitation. Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the manufacturer.
What does it mean when your timing chain rattles?
However, when a timing chain is working its way loose, it causes vibration inside and this sounds like a rattling noise when the engine is idling. A rattle always indicates that something is loose and should always be investigated.
How can I tell if my timing chain is bad?
Once the belts have been removed, start the engine. Place the probe of the stethoscope on the top or side of the timing chain cover. If you hear a rattling or scraping sound, with no other noise being emitted from the engine, it indicates a bad timing chain. Do not run the engine excessively long with the belts off.
When does a timing chain need to be replaced?
Every time you use the engine, the timing chain is in use. When does a timing chain need to be replaced? The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.
Why does my car engine rattle when I accelerate?
As the engine spins inside, the timing belt or chain needs some guidance, especially as the engine revs climb. Engine rattling when accelerating can be a symptom of a problem with this timing belt. There are guides for engines with a timing chain. Both vehicles with a timing belt or a chain have a tensioning system to keep it snug and centered.
What kind of noise does a timing chain make?
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. Such a noise will reveal a loose timing chain hitting the inside of the timing chain cover every time it rotates. You might also hear a metallic slapping noise.
Why does my car make a rattling noise when I start the engine?
Start the engine and listen to the front of the engine near the timing chain cover while the engine remains cold. A bad timing chain will often emit a rattling sound for a few minutes before the engine warms up, and then will lower in intensity or dissipate altogether after it warms up.
Once the belts have been removed, start the engine. Place the probe of the stethoscope on the top or side of the timing chain cover. If you hear a rattling or scraping sound, with no other noise being emitted from the engine, it indicates a bad timing chain. Do not run the engine excessively long with the belts off.

Why is my timing chain making noise when I start the car?
The reason timing chains can be noisy on start up is either the pressure in the oil charged tensioner is bleeding off, or there is extra slop in the chain system that the tensioner isn’t design to take up. Dirty oil can lodge debris in the tensioner that will keep the check valve open bleeding…
Start the engine and listen to the front of the engine near the timing chain cover while the engine remains cold. A bad timing chain will often emit a rattling sound for a few minutes before the engine warms up, and then will lower in intensity or dissipate altogether after it warms up.
How can I tell if my timing chain is stretched?
Move the stethoscope slowly over both valve covers. If all the rocker arms seem noisy, it points to a stretched timing chain. Determine if your vehicle has a single serpentine belt or individual belts running the separate components. Shut the engine off.
Why does the timing chain make a noise when the engine is running?
If the two become misaligned or the connection breaks as the result of a bad timing chain, the engine fails to run properly or won’t run at all. The timing chain can make a variety of noises, and most often other parts of the engine are blamed for timing chain noise.
Is the timing chain the same as the timing belt?
Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt. Most higher-displacement engines have a timing chain as opposed to a timing belt.
What kind of timing chain does a VF 750 have?
SOLVED: 1983 Honda VF 750 noisy timing chain – Fixya 1983 Honda VF 750 noisy timing chain I have an 83 honda v45 Magna 750. The timing chain makes noise when the engine – Honda 1984 VF 750 S question
When did Honda stop making the VF1000F2?
Engine and frame modifications were carried over from the development of the R and FF models, but the F2 still had chain driven cams. The VF1000F2- (F/G) was discontinued in May 1986. FRONT : Air-assist 41mm fork with 3-way adjustable rebound damping.
Why does my timing chain make a rattling noise?
Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover. If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack.
What makes a rattling noise when the engine is idle?
Noisy rattle starting then once engine warms up the rattle comes back at idle. Once engine gets between 1800-2500 rpms it has the same rattle. Rear timing chain cassette was broken causing rattling noise, engine had to be removed in order to repair it.
What does a timing chain do in an engine?
What does a timing chain do? A timing chain synchronizes the rotation of the crankshaft and camshaft (s) ensuring proper timing and allows the engine’s valves to open and close during each cylinder’s firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
Why does my timing chain wear so fast?
Using the wrong oil is a common symptom that causes a vehicle’s timing chain to wear even quicker. Often, modern vehicles will only be able to use synthetic oil because they must meet certain specifications to ensure the oil flows quickly, and with the proper pressure.
Why does my timing chain make a noise?
Move a few inches at a time. Listen for noisy lifters. If all the lifters sound noisy, it means that the timing chain has too much slack in it. This can work for V6 and V8 engines. Move the stethoscope slowly over both valve covers. If all the rocker arms seem noisy, it points to a stretched timing chain.
What to do when your timing belt makes noise?
Remember the timing belt drive may not be the only source for noise. To eliminate the timing belt as the noise problem, spray it with soapy water while it is running. If the noise goes away or decreases, then the timing belt is part of the problem. If the noise is still evident, then the problem is likely due to other drive components.
What should you do if your car is making a clunking noise?
If your car is making a clunking noise, make sure that you don’t ignore it as it may be something quite serious. Putting off getting your vehicle checked out is simply not worth risking the safety of your family .
Timing Chain and Gears. Engines designed with timing gears, or those equipped with a timing chain and sprockets, can produce different noise. The most common noise is a high frequency, light-knocking sound. This sound will generally be the same in intensity whether the engine is idling, operating at high speeds, or under load.
When does a loose camshaft make the loudest noise?
Loose or improperly seated camshaft timing gears are usually loudest when warm. They are speed sensitive only. They are not load sensitive. Cam gear noise will usually be evident at a warm idle in neutral and sounds much like a loose timing chain noise.
