![]() Imagine this happening while you are driving. These are scary symptoms that contribute to more stress on top of the stress of driving.Ī broken timing chain will cause your engine to immediately turn off. If you can’t afford the repair now, avoid driving your vehicle.ĭriving with a failing timing chain could mean dealing with engine misfires, poor accelerating power, and odd sounds from within the motor. Don’t let the fear of this repair persuade you from putting it off. Driving with a broken timing chain is impossible. Will a Car Run with a Failing or Broken Timing Chain?ĭriving with a failing timing chain could lead to several issues. A mechanic needs to inspect the vehicle and recommend necessary repairs. ![]() If the timing chain is loose, it may cause vibration and produce a rattling sound as the engine idles.Ī failing or broken timing chain contributes to poor engine performance. Odd sounds coming from inside the motor indicate a serious warning. You could also ask for a computer read out at an auto parts store. If you see the check engine line, the appropriate course of action is to take the car to a mechanic if the car is still drivable. The check engine light can come on for a variety of reasons including a failing timing chain. In many cases, the problem is so severe and costly that the owner decides to send the car to the junkyard. This could potentially ruin the engine.Įngine replacement is expensive, up to $6000. If the timing chain breaks while driving, the pistons will be damaged from contact with the valves. When you have your oil changed, ask your mechanic if any small pieces of metal were found.Ī broken timing chain will cause an engine to not start. If the timing chain breaks, loose metal rolls around inside the motor which can lead to serious damage. If the timing chain is worn, small pieces of metal can break off and enter the oil pan. Additionally, the engine may run poorly and lack accelerating power. This causes the engine’s timing to fail and often results in a misfire. Normal wear and tear causes the timing chain to stretch meaning the chain to skip a gear on the camshaft or crankshaft. Signs of a bad or failing timing chain include: What Are the Symptoms of a Bad Timing Chain? If you drive an older vehicle, or one close to 100,000 miles, you should have it replaced or at least become aware of the symptoms of a failing timing chain. Unless there is a specific problem, the timing chain normally needs to be replaced between 80,000 and 120,000 miles. ![]() Using the wrong oil can cause extra weight on the chain, meaning the engine will not be properly lubricated. Most modern vehicles only use synthetic oil. If the chain fails, the vehicle will not run at all.įailure can also depend on oil quality. The guides connected to the timing chain can wear out, causing the timing chain to fail. Timing Chains stretch due to normal wear and tear. What Causes a Timing Chain to Break or Wear? If the pistons and valves don’t fire or move when they should, your engine will suffer severe damage and not work. The timing chain controls the pistons and valves, making sure they operate when they need to inside the engine’s cylinders. Every time you use the engine, the timing chain is used too. The timing chain is located inside the engine. This allows the engine’s valves to open and close when each cylinder is fired. What Is the Timing Chain and What Does it Do?Ī timing chain coordinates the rotation of the crankshaft and camshaft.
