What happens if I fail my timing chain?
The downside to chains is that if they fail, they cause a lot more damage than a rubber belt failure. Either scenario is not good, and both can require costly repairs – but a failed timing belt might only result in engine header repairs, whereas a failed timing chain might require a complete engine replacement (or a new car, if you prefer).
Can a timing belt be replaced with a chain?
In larger engines that put out more power the timing belt is replaced with a timing chain, which looks much like a bicycle chain. Metal chains serve the same purpose as belts but last a lot longer. Some manufacturers recommend changing the chain at certain intervals, but not the same as for rubber timing belts.
How can you tell if your timing belt is bad?
How to tell if your timing belt is bad. Timing belts don’t often give you a lot of warning when they’re about to give way – they might squeak or chirp, or they might just suddenly break. More often, though, damage is due to wear in the timing belt. You can do a visual check – see if there’s any cracking, glazing, missing teeth or oil contamination.
Why does my timing belt tensioner not work?
Community Answer. The timing chain tensioner is a part that requires a lot of work to change. That’s caused by the necessary time to reach the tensioner and to synchronize the chain, which is in the engine, not as a belt that is external.
Can a bad timing belt cause engine damage?
A bad timing belt or timing chain can be a serious issue. If it jumps a tooth, or breaks entirely it can lead to permanent engine damage. It’s important to know the symptoms of a bad timing belt or chain, so this doesn’t happen to your Mazda BT-50.
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.
When do you need to replace timing chain belts?
Volkswagen’s own warranty and maintenance schedules say you shouldn’t have to worry about timing chain maintenance for 120,000 miles. That’s one of the main reasons chains have replaced belts in high-displacement engines. The most likely cause is a timing chain tensioner failure.
What happens to timing chain when tensioner fails?
If the tensioner fails and the chain becomes loose, the timing of the engine is thrown off. Whether the timing chain itself has stretched, or a tensioner isn’t doing its job, the result is the same. Here’s some tell-tale signs of a timing chain problem.
