Like a pacemaker, the timing chain ensures that everything in your engine runs smoothly and efficiently.
This
chain allows all motor components to communicate with one another and prevents
them from damaging or colliding with other engine components. Everything could
be thrown off kilter if one step is missed.
That
being said because the timing chain is such an important part of your vehicle's
engine, keeping it in good condition is a top priority and an important part of
your vehicle's maintenance process and car service in Reading. With that
said, here is a quick guide to understanding what a timing chain is and what it
does in relation to your vehicle's engine.
What exactly is a timing chain?
It
is a metal chain that uses engine power to drive the camshaft. It is much
quieter, lighter, and requires less maintenance than its rubber belt
counterpart. Timing chains are also known for their longevity and durability
because they do not need to be replaced as frequently as their rubber-based
timing belt counterpart. These will also frequently last the life of a car with
minimum maintenance.
What is the purpose of a timing chain?
A
timing chain synchronises the position of an engine's pistons and camshafts in
the same way that a timing belt does. It ensures that the motor is properly
timed and allows the engine's valves to open and close in accordance with the
engine's combustion process. The chain is located inside the engine and
must be kept lubricated at all times to prevent wear and tear.
When should you replace a timing chain?
Because
this part lasts longer than a timing belt, it will be replaced between 120,000
and 150,000 miles on a vehicle. However, this is still dependent on the engine
and the manufacturer's specifications. It is also critical to keep the timing
chain lubricated because using the incorrect viscosity oil can damage the
timing chain pins and plates.
While
a timing chain is more durable than a timing belt, signs of stretching or
failure are slightly more difficult to detect. It is also more difficult to
cause a timing chain to jump teeth, causing the engine to run out of sync. Here
is a quick checklist of warning signs that it may be time to replace a timing
chain:
1. The engine fails to start
or runs poorly - This could indicate that the engine's timing is off
because the valves aren't properly in sync with one another, leaving a small
gap between the combustion process.
2. Metal shavings are found
in the oil - Looking at the oil in the engine during an oil change is a good
way to see if a chain is failing. If there are metal shavings in the oil, it
could mean that the timing chain has been stretched and is about to fail. It
could, however, be a sign of something else, so keep that in mind when
inspecting the oil.
3. The engine won't start or
won't idle - A broken or damaged timing chain will prevent the engine from
starting or will cause it to fail while driving. If this occurs, your engine's
timing may be thrown off, and the pistons may come into contact with the
valves, resulting in a costly repair and impairing your vehicle's movement.
4. The check engine light is
illuminated - The check engine light is another indicator of a stretched or
damaged timing chain. The vehicle's computer will illuminate this warning light
only if it detects a problem with the vehicle. If its sensors detect a problem,
the light will illuminate, requiring immediate attention and a scan to
determine the source of the problem.
5. Listen for unusual
rattling noises from the engine while it is idling – This is one audio way to
determine if your timing belt is failing. A normal engine should produce a
consistent and smooth sound, indicating that everything is working properly.
When a timing chain becomes stretched, it causes vibrations inside the engine,
resulting in a rattling sound as the engine idles. Timing Belt Cost
What should I anticipate from a timing chain replacement?
When
your timing chain needs to be replaced, the engine must be opened up or even
removed from the vehicle. Aside from the costly repair bill for parts and
labour, expect the car to be out of commission for a few days as this process
may take a few days to complete. It is important to note that the availability
of the car service centre will also be a factor. Aside from the initial
process of replacing the timing chain, expect your vehicle to go through a
short break-in period to ensure that everything is working properly. This is
done to ensure that the installation process was completed correctly and that
nothing else needs to be addressed afterward. Timing belt change
