What causes a timing chain to skip?
If a valve is open or the plugs don’t fire at the right time the air and fuel that have entered the combustion chamber are not going to ignite. Most timing chains use a tensioner to keep them tight and to keep them from jumping. If something happens to the tensioner, it can cause the timing chain to jump prematurely.
How many miles does a timing chain last?
The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.
What happens when a timing chain jumps?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all.
What causes a car’s timing chain to fail?
Furthermore, 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. One cause of the timing chain wearing out faster, is using the wrong oil.
Why do I need to change the oil in my timing chain?
Timing chain pin and plate wear is accelerated by contaminates in the oil, that is the reason frequent oil changes are required. It is not that the old oil doesn’t lubricate, particulates that get trapped in the oil that work between the pin/plates will create accelerated wear.
What should I do if my timing chain breaks?
You’d probably be better off either purchasing a new engine or trading in your car for a new one. If you have a non-interference engine, the result of a broken timing chain will not be as severe.
Where is the timing chain located in an engine?
The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well. Every time you use the engine, the timing chain is in use. When does a timing chain need to be replaced?
