What is the lifespan of a timing chain tensioner?
Re: Timing Chain Life Span? It's the tensioner which gives up not the chain. It's a duplex chain running in oil, should last 100k miles with no problems.
How do I know if my timing chain tensioner is bad?
Yes you could, if your vehicle has a history of timing chain tensioner issues. But if not , theres no need replacing them. Though I've worked on a vw that had a timing chain tensioner issue, the engine skipped timing due to a bad tensioner and the valves and piston jamed.
Can I replace timing chain tensioner without replacing timing chain?
Usually, timing chain tensioners simply wear out over time. A tensioner may also become over-extended if the timing chain is stretched.
Do timing chain tensioners wear out?
Most cars will go well past 100,000 miles before timing chains become a problem. If they have had regular oil changes from the time they were new, you shouldn't have to worry about the timing chain for a good while.
Can a timing chain last 500000 miles?
A timing chain should easily last the life of the engine, well over 100,000 miles even upward of 250K, other parts will wear out or fail first.
Can a timing chain last 200 000 miles?
Signs of a Bad Timing Chain
Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off.
Is there a warning before a timing chain breaks?
What happens if a timing belt tensioner fails? It will jump a tooth if the tensioner is loose. And if the engine is interference tolerance between the valves and pistons there is a good chance that you will at best bend valves and at worst hole a piston and seize the engine.
What happens if you don't replace timing chain tensioner?
Once you did that you may as well replace it if there is any doubt about its condition. Is it safe to drive with a bad timing chain tensioner? Probably not because your timing chain could jump or break (particularly at high mileage) which would leave you stranded with engine not able to run.

What does a bad timing chain tensioner sound like?
It's always a good idea to change timing belt with its other elements such as idler or tensioner.
Should I replace tensioner with timing belt?
A timing chain looks a bit like a bike chain and can be lubricated with engine oil. Tensioners controlled by oil pressure in the engine hold the timing chain in place. If the oil pressure is low, the chain tensioners can lose pressure and offset engine timing.
What is the difference between a timing chain and a tensioner?
Going too long between oil changes and using the wrong type or viscosity rated motor oil causes the timing chain pins and plates to wear, resulting in timing chain stretch. Timing chain pin and plate wear is accelerated by contaminates in the oil, that is the reason frequent oil changes are required.
Does frequent oil changes help timing chain?
Timing chain installation requires the right tools, a service manual specific to the engine's model and a degree of mechanical know-how. Because it is a major job, the risk of performing it incorrectly could trigger irreversible consequences for the engine.
Is replacing a timing chain a big job?
Frequent oil changes, and using a good quality oil will increase timing chain life. Some of the oil life monitors on modern cars set the oil change interval too long and cause excess timing chain wear. I know for some vehicles the programming has been changed because of excess chain wear.
How can I make my timing chain last longer?
As a timing chain is lubricated by engine oil, changing your car's oil at the recommended intervals can help extend the chain's life. Of course, if you buy new cars and only keep them for 50,000 miles or less, none of this is as likely to affect you.
How can I extend the life of my timing chain?
Oftentimes, other parts will need to be replaced, too. The tensioners and guides that hold the chain in place and the crankshaft and camshaft sprockets will likely be replaced at the same time as the timing chain, for example. Cost of these parts and time to replace them can increase your overall bill.
Why is it so expensive to replace timing chain?
With patience and some free time, even a beginner can get this maintenance done. If you've got a Saturday free, you can save nearly $1,000 by doing it yourself. Similar to a bicycle chain, the timing chain is a critical component connecting the crankshaft and camshaft, allowing them to rotate together.

Regular maintenance is essential to prevent this from becoming a more serious problem. Lack of Maintenance: Neglecting regular oil changes and maintenance can accelerate timing chain wear and lead to premature failure.
Will thicker oil stop timing chain noise?
There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. However, you should inspect your tensioner each time you service your car to monitor its condition and replace it if necessary.
How do you prevent timing chain failure?
Can a timing chain cause a rough idle? - Quora. However, when the timing chain is loose, it may cause a vibration inside the motor and that will produce a rattling noise as the engine idles.
Should I replace tensioner?
Rattling on cold start up is usually an indication of a timing chain issue. Timing chains synchronize the crankshaft and camshafts so they rotate at the proper time for the engine to run properly.
How do you diagnose a bad tensioner?
One of the leading causes of timing chain issues in cars is wear and tear. As the timing chain is made up of metal links, over time, they can stretch or even break. This can cause a loss of tension, leading to improper synchronization between the crankshaft and the camshaft.
Can a bad timing chain tensioner cause rough idle?
Different makes and models of cars come with either a Timing Chain or a Cam/Timing Belt. The main difference is the Timing Chain can last anywhere from 120 000km to 200 000km and is made of metal. While the Cambelt is made of rubber and can only last between 60 000km and 160 000km.

What else should be replaced when replacing timing chain?
Timing chains are not typically a maintenance service that needs to be replaced after so many miles or years like a timing belt. The best way to maintain an engine and therefore the timing chain if it is equipped with one, is to keep the oil in the engine fresh and clean with regular oil changes.
How do you check a timing chain tensioner?
Timing chains are overall more reliable and durable than timing belts; however, it's always good to have them inspected between 74,500 – 93,000 miles and to change the oil regularly to ensure that everything is running smoothly and thus prevent premature failure.
