How long can a bad timing chain last?
How long can a bad timing chain last?
between 40,000 and 100,000 miles
The metal links in the chain move on the tooth sprockets on the end of the crankshaft and crankshaft so that they rotate together. The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem.
Why does my car have a failing timing chain?
One reason is a failing timing chain. The computer in your car detects that something wrong with the way in which the engine is working. When the timing chain is stretched, it makes the engine perform poorly and so the engine emissions are increased.
How often should a timing chain be replaced?
The age and number of miles driven on a timing chain are major contributors to failure. The more miles you have on your vehicle, the higher the odds your timing chain will fail, as the chain will become weak and break. Most car manufacturers suggest you have the chain replaced every 60,000 miles.

What actually causes a timing chain to go bad?
- Tension. A timing chain can break with either too much or not enough tension.
- causing pistons to seize inside the cylinders.
- Age. The age and number of miles driven on a timing chain are major contributors to failure.
What are the symptoms of a bad timing chain?
