What happens when timing chain breaks?
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
When do you Know Your timing chain needs to be replaced?
Signs your timing chain needs to be replaced include: Your vehicle has a rough idle, meaning your engine shakes. Your car backfires. The vehicle seems to be working harder than normal. Your car will not start at all, indicated a complete timing chain failure.
What are the symptoms of a bad timing chain?
Symptoms of a Bad or Failing Timing Chain. 1 1. Engine misfires or runs poorly. There are two ways to achieve valve timing in a combustion engine. The first is the two-gear method, which includes 2 2. Metal shavings found in the oil. 3 3. Engine won’t start or fails. 4 4. Check Engine Light is on. 5 5. Engine rattles while idling.
Can a 4.0L SOHC engine bend the timing chain?
Fortunately, the 4.0L SOHC is not an interference engine so a timing chain failure won’t bend the valves. But it does create an expensive repair for the vehicle owner.
What should I do if my timing chain rattle?
If the engine in your customer’s vehicle has a timing chain rattle problem, and the engine has less than 100,000 miles on it, doing an oil change and using a light viscosity, pure synthetic oil can sometimes quiet the noise. The lighter oil will flow to the timing chain more quickly following a cold start and reduce the noise somewhat.
What are the symptoms of a failing timing chain?
The Symptoms of a Failing Timing Chain: What There Is To Know! If you turn the key in your engine and hear a loud ticking sound, don’t panic, it is not necessarily a bomb.

Where is the timing chain on a car?
The chain (sometimes referred to as a “belt”) is located in the car’s engine and controls the opening and closing of the exhaust and intake valves. The chain must be accurately aligned due to the fact that the piston must be synchronized completely with the valves.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
Which is a disadvantage of a timing belt?
The main disadvantage of a timing belt (as opposed to a chain) is that they deteriorate quickly. Because of this, there’s a higher risk of damage being caused to the engine unexpectedly. In recent years, manufacturers have started to return to using timing chains again. What Will Happen if the Timing Chain Goes?
