Signs of a Faulty Timing Chain
- Rattling Sound on Starting the Engine or Idling. A common finding in a vehicle with a bad timing chain is unusual rattling noise when the engine is started or when brakes are engaged. …
- Misfiring Engine. …
- Contaminated Engine Oil. …
- Check Engine Light. …
- Inability to Start the Engine.
Subsequently, How can you tell if timing chain is bad? Common signs of a faulty timing chain include engine misfires, metal shavings found in the oil, and rattling sounds from the engine while idling.

How does a car act when the timing chain is going out? When a timing chain is loose or stretched, you might experience misfires while driving because the timing between the valves and pistons is out of sync, which affects the combustion in the engine. A stretched chain can skip a gear on the cam or crankshaft so that the engine’s timing falls out of calibration.
Yet, What does a worn timing chain sound like? 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.
How do you check a timing chain? To accurately identify the amount of wear in a timing chain, begin by removing all of the spark plugs and the distributor cap. With a wrench on the harmonic balancer bolt, turn the crankshaft at least two complete revolutions backward of rotation to remove any slack from the timing chain.
What causes a timing chain to fail?
What causes a timing chain to break or wear? Over time, the timing chain stretches due to internal component wear. The chain tensioner or the guides that are connected to the timing chain may wear out as well, causing the timing chain to fail completely. If the chain fails, the vehicle will not run at all.
Can you drive with a noisy timing chain?
Can you 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.
Will thicker oil stop timing chain noise?
You can’t fix a timing chain issue (whatever it may be) with an additive. Usually, using a heavier oil can quiet down things like lifters, but I don’t think that would do much, if anything at all, with your timing chain noise. And a heavier oil may have some undesirable side effects.
How long should a timing chain last?
A timing chain can last more than 200,000 miles when looked after well. As it is made of metal, it has much more longevity than a timing belt. While you may never need a timing chain replacement, you should book a check when your car reaches 125,000 miles and invest in regular oil changes to keep it well-lubricated.

What causes a timing chain to break or wear? Over time, the timing chain stretches due to internal component wear.

Is it better to replace timing chain or engine?
A: As a general rule, if an engine has a timing chain and the oil was changed on a regular basis, the timing chain should last the lifetime of the engine.
How many miles does timing chain last?
The metal links in the chain move on the tooth sprockets on the end of the crankshaft and crankshaft so that they rotate together. The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem.
