Lifter on Car Engine
What is a Lifter?
A lifter is a mechanical device that is used to raise and lower the valves in a car engine.
Lifters are located between the camshaft and the valves, and they are responsible for opening
and closing the valves at the correct times.
How Do Lifters Work?
Lifters are typically actuated by the camshaft, which is a rotating shaft that has a series
of lobes on it.
As the camshaft rotates, the lobes push against the lifters, which in turn raise the valves.
When the lobes pass by the lifters, the valves are closed by the valve springs.
Types of Lifters
There are two main types of lifters:
- Solid lifters are made of a single piece of metal, and they are not adjustable.
- Hydraulic lifters are filled with oil, and they are adjustable.
Hydraulic lifters are able to automatically adjust their clearance, which helps to reduce
noise and wear.
Lifter Problems
Lifters can fail for a variety of reasons, including:
- Worn lobes on the camshaft
- Damaged lifters
- Low oil pressure
- Dirt or debris in the oil
Symptoms of Lifter Problems
The following are some symptoms of lifter problems:
- Ticking or clicking noise from the engine
- Loss of power
- Rough idle
- Check engine light
Lifter Replacement
If you suspect that your lifters are failing, it is important to have them replaced as soon as
possible.
Replacing lifters is a complex process, and it is best left to a qualified mechanic.
Lifter Maintenance
The best way to prevent lifter problems is to follow the manufacturer’s recommended maintenance
schedule.
This will help to ensure that your lifters are properly lubricated and adjusted.
