Is it safe to drive with a bad timing chain tensioner?
You absolutely should not continue to drive with a bad timing chain tensioner. Doing so can cause catastrophic engine damage and potentially leave you stranded.
How long can I drive with a bad timing belt tensioner?
Well, you COULD drive it until the tensioner gets so bad that the belt either slips a few teeth or tears itself to bits. Either of these will cause your engine to lose critical valve timing. If you're lucky the result will only be bent or broken valves and severely damaged pistons.
What happens if you don't replace timing chain tensioner?
When the timing chain gets loose from streching or failed tensioners, it will jump timing. That will make the engine not run properly to not at all. It can also result in engine replacement due to internal damage from parts colliding.
What happens when chain tensioner fails?
If the tensioner fails, it will no longer hold tension on the timing chain. Depending on the situation, this can lead to a rattling sound, but it could also allow the chain to jump and cause the engine to shift out of time. In that case, you may experience backfires and the check engine light will usually come on.
How long can I drive with a rattling timing chain?
As we explained in this article, there is no good answer to how long can you drive with a bad timing chain. You should not plan any other journey before our auto repair technicians look at your engine and fix or replace the timing chain. If the chain fails in the middle of a busy expressway, your life may be at risk.
Can you drive without timing chain tensioner?
Not a good idea……. The tensioner keep 'tension' on the timing chain, preventing it from coming off. If that tensioner breaks and the timing chain goes slack and it jumps off of the cams while running, the engine will likely be toast, which could have been avoided by replacing a $30–40.00 tensioner.
What does a bad timing chain tensioner sound like?
There will be a rattle sound from the engine as it slaps against chain guides, can also rub on case cover. I have see this in the trade. This will also happen if the tensioner goes bad.
How long does a timing chain tensioner last?
Timing chain tensioner adjusters, when well-maintained, can last between 120,000 to 160,000 kilometers. However, driving conditions, maintenance habits, and the quality of parts used can affect their longevity.
Is there a warning before a timing chain breaks?
Signs of a Bad Timing Chain
Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off.
Can a timing chain last 200 000 miles?
A timing chain should easily last the life of the engine, well over 100,000 miles even upward of 250K, other parts will wear out or fail first.
Can I just replace timing chain tensioner?
Yes you could, if your vehicle has a history of timing chain tensioner issues. But if not , theres no need replacing them. Though I've worked on a vw that had a timing chain tensioner issue, the engine skipped timing due to a bad tensioner and the valves and piston jamed.
Can a bad timing tensioner cause loss of power?
With most belt drives a faulty tensioner will always result in power loss as the belt slips. If tension is too high there will be extra friction and short belt life. If there is extra frictions in bearing on the system it will cause belt slippage and power loss as well.
How does a car act when the timing chain is going out?
A bad timing chain can produce a noticeable ticking or rattling noise coming from the engine. This noise usually increases in intensity as the engine RPMs rise, and it's a clear sign that your timing chain may need attention.
Can a bad timing chain tensioner cause rough idle?
However, when the timing chain is loose, it may cause a vibration inside the motor and that will produce a rattling noise as the engine idles. Anytime you hear a rattle it means something is loose and needs to be fixed before it breaks.
How do I know if my timing belt tensioner is bad?
When the tensioner becomes faulty, the belt and pulleys can generate high-pitched whining or chirping noises due to the belt rubbing on the pulleys. If the tensioner fails completely, the noise might escalate into squealing or grinding.
Can a timing chain last 300000 miles?
Start thinking about a timing chain at 300k miles. But with a chain - it'll start to make noise to let you know it needs changing. Sure some vehicles the chain will last much longer. But we've seen people in this forum who put over 200k miles on their timing belt before it needed changing.
Does a bad timing chain rattle all the time?
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.
What happens if you keep driving with bad timing belt?
When your timing belt is broken, you won't be able to drive your car at all. Oftentimes, the timing belt will break while the car is in motion. This can cause serious damage to cylinder head hardware like rocker arms, push rods, or valves.
Will thicker oil stop timing chain noise?
If the noise is caused by worn lifters, you may be able to quiet it down by using a thicker oil. If the noise is caused by other problems, such as worn camshaft bearings, then thicker oil will not help.
How can I make my timing chain quieter?
As standard, they adjust themselves automatically, but occasionally they fail. You don't quiet it. You replace it and all associated parts - the chain itself, idler pulley or pulleys, and tensioner .
Does timing chain noise go away when warm?
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. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.
Can you check timing chain tensioner?
A timing chain looks a bit like a bike chain and can be lubricated with engine oil. Tensioners controlled by oil pressure in the engine hold the timing chain in place. If the oil pressure is low, the chain tensioners can lose pressure and offset engine timing.
What is the difference between a timing chain and a tensioner?
The long answer is maybe. Example: If late timing contributed to a rich condition and the additional carbon eventually stuck the piston rings then oil consumption could go up. Until that happened though any oil consumption due to cylinder pressure changes or temperature would be insignificant.
Can a bad timing chain burn oil?
If the valves weren't smashed by the pistons, just un-jump the timing. When an engine jumps timing it means the timing belt or chain skips to the next tooth on the sprocket. To make it “not jumped” anymore the belt/chain just needs to be moved back onto the correct teeth.
Can you fix an engine that jumped timing?
My experience has been that by the time the chain is loose enough to need attention (300K to 500K miles) the engine needs to be rebuilt anyway. There are exceptions. There are some designs with plastic tensioners that can fail at the 150K range and cause major engine damage.
Can a timing chain last 500000 miles?
Usually it's well worth replacing the timing chain if it has failed , but hopefully it's replaced as maintenance care before something is damaged. Some engines are interference engines , meaning if the timing of the camshaft (s) became out of time the valves may be damage by the pistons striking them.
Is timing chain worth fixing?
A worn timing chain will show some obvious engine problems. You might notice misfires and reduced performance, metal shavings in the oil, or a loud rattle from the front of the engine. Changing a timing chain is not outright difficult but is considered a complex job due to the large number of steps involved.
Is replacing a timing chain a big job?
Just like any other misfunctioning component of the engine, a faulty timing chain will illuminate the check engine light. It is a warning to get your vehicle assessed for underlying engine problems, which might include a bad timing chain.
Will a bad timing chain tensioner throw a code?
If you have a front derailleur, you will need a tensioner. It will not let the chain go slack when you change the crank sprockets. But if you have a rear derailleur, you need not have a tensioner as the derailleur itself is a tensioner. You can adjust the tension in the chain.
How important is a chain tensioner?

What happens if you don't replace tensioner?
Unless there is a specific fault, the timing chain should be replaced between 80,000 and 120,000 miles. Chain problems are frequent in automobiles with increasing mileage. If you're driving an older car or one with a lot of miles on it, keep an eye out for signs that the timing chain is failing.
How long does it take for a timing chain to break?
Due to engine oil lubrication, most OEMs view timing chains as 'fit for life', excluding them from service inspection and warranty replacement. If timing chains are forced to operate under low oil pressure conditions, however, this can lead to serious component wear and eventual catastrophic failure.
Can low oil cause timing chain to break?
And, if the timing chain becomes loose, you can get ready for serious and costly problems. If the timing chain breaks or jumps while you are driving the car, the pistons will be damaged from contact with the valves, the valves will bend, and potentially ruin the engine.
