In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight. It’s even more difficult in a V6 engine.
Can I change timing chain myself?
You may find the need to replace your timing chain at some point; however with the right tools, a service manual and some mechanical know-how, you can do it yourself. Just be aware that this is a major job and can have serious consequences for your engine if done incorrectly.
How much does it cost to change a timing chain?
On average, you’re going to be looking at paying somewhere between $1,290 and $1,550 for a new timing chain for your car. That price includes all the necessary parts, which will run you just under $400, and labor, which is going to cost more than $1,000 in many cases.
How long does it take to change a timing chain?

What are the signs of a bad timing chain?
Common signs of a faulty timing chain include engine misfires, metal shavings found in the oil, and rattling sounds from the engine while idling.
Engine misfires or runs poorly.
Metal shavings found in the oil.
Engine won’t start or fails.
Check Engine Light is on.
Engine rattles while idling.
Do I need to change a timing chain?
The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Over time, the timing chain wears out because it stretches. 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.
Will a new timing chain improve performance?
Replacing them with new components can give the false feeling of increased performance when the truth is the engine has just been returned to the correct state of operation. No timing belt will give an increase in performance – it’s just not possible. Its main job is to keep the timing in check.
Can you tighten a timing chain?
Can You Tighten A Timing Chain? Timing chains can be adjusted to either loosen or tighten the timing chain so that it runs smoothly along with the timing chain tensioner.
How do you check a timing chain?
How do you reset timing chain?

There are also timing sets which include the gears you need that can cost anywhere from $15 to $250.
What does a bad timing chain sound like?
Engine rattles while idling
Under normal conditions, the engine should have a consistent, smooth sound that indicates everything is running as it should. However, when the timing chain is loose, it may cause a vibration inside the motor and will be indicated by a rattling noise as the engine idles.
Will check engine light come on for timing chain?
Illuminated check engine light: The car’s computer monitors engine operation to ensure emissions don’t get too high. A stretched timing chain will hurt engine performance and increase emissions. If this happens, the computer will turn on the check engine light and store a diagnostic trouble code.
What causes a bad timing chain?
The most common cause of timing chain stretch is lack of maintenance and regular oil changes. Worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other. In some cases, a worn timing chain may cause the engine to jump time a few teeth.
What is the code for a bad timing chain?
It does this by monitoring them using the Camshaft Position Sensor(s) and Crankshaft Position Sensor. If the Engine Control Module (ECM) detects that the bank 2 camshaft and crankshaft are not in the correct position, it will trigger code P0009.
How do you know if your timing chain is stretched?
Signs of a Stretched Timing Chain
Backfiring. If your engine backfires, it could be due to a loose timing chain.
Power Loss. If your vehicle loses power, without warning, your timing chain might be loose.
Check Engine Light.
How do you fix a timing chain jump?
If the timing chain jumped a tooth, then the cam is no longer in time with the crankshaft. You may be able to adjust the distributor to be in time with the crankshaft but the valve timing will be off. Best to pull the timing cover off and replace the timing chain & gears with a new one.
What happens if timing chain is off by one tooth?
If the chain only jumps one tooth, then the car might even run it just won’t run right. If the timing chain has jumped, you can start the car with he hood open and see if it takes the engine longer then normal to turn over. Also, you can pay attention to if there is backfiring in the engine.
How long will a bad timing chain last?
When does a timing chain need to be replaced? 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.
Will engine run if timing is off?
If the timing is off, damage can occur. In some engines, called “interference engines,” the consequences can be especially bad. You could end up having to have your engine rebuilt, or even replaced. If your cam timing is off, chances are you’ll know because your car will not be running well, if it’s running at all.
