When the timing chain is loose, however, it can cause a vibration inside the engine, resulting in a rattling noise when the engine idles. The engine should make a constant, smooth sound under typical circumstances, indicating that everything is working properly.
Unusual noises are also a regular indicator of a problem with your vehicle’s engine.
Bad timing chain symptoms code#
The code will need to be examined by a mechanic, who will then prescribe the necessary repairs. A strained timing chain causes poor engine performance and higher emissions, causing the check engine light to illuminate and a diagnostic fault code to be stored. When the onboard computer identifies a problem with the emissions system or engine operation, the check engine light may illuminate. Warning lights on a car’s computer must be checked and trouble codes scanned to pinpoint the source of the problem. The check engine light can come on for a number of causes, one of which being a broken timing chain. If your engine won’t start or starts driving erratically, it’s time to take it to a trained mechanic for an inspection and repairs. If the belt has become loose, it might flail around and cause harm to other sections of the engine. The valves will bend, perhaps destroying the engine. The pistons will be damaged by contact with the valves if it breaks or leaps while driving. If the belt is already broken, the engine will not start due to a lack of compression. When you get your oil changed and the mechanic tells you that there were small pieces of metal in the oil as it drained or in the filter, it’s a sign that your timing chain is failing.Īn engine with a broken timing chain will not start or will fail while driving. Small metal pieces can break off the timing chain and find their way into the oil pan if it begins to wear down. As oil heats up and is exposed to natural solvents inherent in gasoline, it begins to separate. The loose metal moving about inside the motor if the timing chain breaks might cause catastrophic engine damage.Įvery 3,000 to 5,000 miles, all automobile manufacturers recommend changing the engine oil and filter. If this happens, the timing chain is most likely destroyed and needs to be changed as quickly as possible. It’s also possible that the engine will operate badly and lack accelerating power. This causes the engine’s timing to become out of whack, resulting in a misfire.
The timing chain can stretch with time, causing the chain to skip a gear on the camshaft or crankshaft. Consumer automobiles with high-performance engines are more likely to use the timing chain approach. This is the method employed in the majority of heavy machinery and large trucks. The first is the two-gear technique, which involves a direct connection between the crankshaft and camshaft gears. In a combustion engine, valve timing can be achieved in two ways.

It’ll set you back a few hundred dollars to fix it. Depending on the vehicle, a timing belt should be replaced between 40,000 and 100,000 kilometers. Because it needs to be lubricated by engine oil, a timing chain runs inside the engine. A timing chain, like a bicycle chain, is comprised of metal. We all know that an automobile engine’s timing belt needs to be replaced at regular intervals, but what about the timing chain? What’s the difference between a chain and a timing belt? A timing belt is a toothed rubber belt that travels outside of the engine and is protected by a protective cover.
Bad timing chain symptoms plus#
In this article, we are going to consider some of the symptoms of a bad timing chain plus many other information you need to know about timing chain. The timing chain is made up of numerous links that travel smoothly across gears, but because it plays such a dynamic function in the motor, it is prone to wear and tear and can cause issues.
