If you are experiencing an unusual sound when starting your vehicle, the timing chain is most likely the cause. A subdued, slapping noise, often punctuated by a soft click, is generally superimposed over a general rattle. The sound tends to be hollow, not loud, and is usually not indicative of a worn chain. In fact, it’s often a combination of worn sprockets and guides as well. Because a worn chain does not necessarily mean imminent failure, hands-on inspection is necessary.
Symptoms of a bad timing chain
A rattling noise coming from the engine when the engine is started or brakes are applied may indicate that the timing chain is failing. A timing chain is responsible for the timing of the opening and closing of each engine valve. When it breaks, the engine cannot get an adequate balance of air and fuel, causing an unbalanced power output. Other signs of a damaged timing chain include metal shavings in the engine oil, which are also indications of a bad timing chain.
If you notice a rattling noise coming from the engine while idling your car, you need to diagnose the cause of the problem. Rough idling may be the result of other problems, but if it doesn’t get better over time, it might be a timing chain problem. Another sign of a bad timing chain is engine rattle, which can happen when the engine is idling or not. If you notice any of these symptoms, you should take your car in for a quick inspection.
The timing chain is a vital part of your car’s engine. Failure can result in severe damage to your engine. A professional mechanic can replace your timing chain if you notice any of these warning signs. Timing chain problems are not uncommon, but preventive maintenance will keep your vehicle running at peak efficiency. You can save thousands of dollars on repairs by replacing the timing chain before it becomes a problem.
Causes of a bad timing chain
When your car makes a rattling noise, it may be the timing chain. This problem typically develops gradually and can be very subtle.

In the event that you’re experiencing this problem, contact a qualified service technician as soon as possible.
A rattling noise: If your car makes a rattling noise while idling, it is most likely the timing chain is damaged or lax. A rattling noise will start and stop intermittently, but it is an indication that the timing chain is bad. The noise could be coming from the crankshaft, clutch, or transmission, or it could also be from the brakes.
A misaligned or broken timing chain can cause an engine to overheat, or even fail. In a high mileage vehicle, you need to have it replaced between eighty thousand and one hundred thousand miles. A broken timing chain can result in expensive engine repair bills. Checking the timing chain is one of the most important steps you can take to avoid this problem. A broken timing chain is the most common cause of engine failure.
When to replace a timing chain
One of the first things you should do if you notice your car making a loud noise is to check the timing chain. Generally, timing chain problems occur in vehicles that have 80,000 to 120,000 miles. If the noise persists or your engine is running poorly, you should consider replacing the entire timing chain. Many vehicles with high mileage will experience timing chain issues. For this reason, it is important to know the symptoms of timing chain failure so you can determine whether it is time to replace your car’s timing chain.
The first sign of a bad timing chain is a rattling noise that occurs before and after the engine warms up. The noise could also be coming from the rocker arms. If you hear these sounds, it’s a good indication that your timing chain is stretched and needs to be replaced. For more information on the causes of timing chain noises, read the rest of this article. Once you’ve done this, you’re well on your way to fixing the problem.
The next sign that you need to replace your timing chain is a warning light. The Check Engine Light will illuminate if your valve timing goes beyond preset limits or if your exhaust emissions are too high. Ignoring this warning could result in severe damage to your engine. In many cases, timing chain noises are an indication that your timing chain has failed, and you should replace it as soon as possible. Noises can be caused by one of three issues: an overly tight tensioner, a mis-adjusted sprocket, or excessive wear on the chain.
