When replacing a camshaft, it is important to consider all the other components in the engine that may be affected by the change and replace them as necessary to ensure the proper function and longevity of the engine.
How long will a camshaft last?
The lifespan of a camshaft can vary greatly depending on a number of different factors. Generally speaking, camshafts are designed and built to last for a long time, and can often last for hundreds of thousands of miles if they are properly maintained and used.
One of the biggest factors that can affect the lifespan of a camshaft is the type of engine it is used in. For example, high-performance engines often put greater stress and strain on the camshaft, which can cause it to wear out more quickly than in a lower performance engine. Similarly, engines that are used in heavy-duty applications, such as trucks or other commercial vehicles, may experience more wear and tear on the camshaft than those used in lighter-duty applications.
Another important factor that can affect the lifespan of a camshaft is the quality of the materials used in its construction. Camshafts are typically made from a variety of materials, including steel, cast iron, and even exotic materials like titanium. Camshafts that are made from higher-quality materials are generally more durable and longer-lasting than those made from lower-quality materials.
In addition to the quality of the materials used in its construction, the design of the camshaft can also play a significant role in how long it lasts. Camshafts that are designed with more aggressive profiles, or that have a greater lift and duration, can put more stress on the valve train and other components of the engine, which can lead to premature wear and damage.
The lifespan of a camshaft can vary widely from one engine to another, and there are a number of different factors that can influence how long it will last. With proper maintenance and care, however, a camshaft can often last for many years and hundreds of thousands of miles, even in high-performance or heavy-duty applications.
What happens if you don’t fix a camshaft?
The camshaft is an essential component in the internal combustion engine of a vehicle. It controls the opening and closing of the valves, which regulates the intake of fuel and the exhaust of combustion gas. Therefore, if you don’t fix a camshaft, it can result in various problems that can significantly impact the engine’s performance and longevity.
First, a malfunctioning camshaft can cause improper valve timing, which means the intake and exhaust valves may not open and close at the right time. If this occurs, the engine won’t be able to perform at its optimum level as it will not be able to operate efficiently. This can lead to reduced fuel economy, loss of power, and ultimately, engine failure.
Second, a defective camshaft can cause engine misfires, which can be a dangerous situation. When the camshaft is not operating correctly, it can cause the intake valve to open when it shouldn’t, which can allow unburned fuel to enter the combustion chamber. This fuel can ignite randomly, causing a misfire, which can result in severe damage to the engine and other parts of the vehicle.
Third, a damaged camshaft can lead to increased emissions.
What causes camshaft failure?
Camshaft failure can be caused by a variety of reasons. Some of the common causes of camshaft failure are excessive wear, poor lubrication, insufficient oil pressure, bending or cracking due to excess stress, and failure of the timing chain.
Excessive wear is one of the critical reasons leading to camshaft failure. This can occur due to lack of maintenance, usage beyond regular life expectancy, and inadequate oil quality or oil changes. If the camshaft is not oiled entirely or lubricated with inferior oil, it can quickly wear out, especially during high RPM use.
Another significant contributor to camshaft failure is poor lubrication. Oil pressure plays a crucial role in the action of camshafts. If the oil pressure is low, the camshaft may rub against the bearing and wear out abnormally. Insufficient oil supply to the camshaft also leads to inadequate lubrication.
Insufficient oil pressure is another potential reason. When the oil pressure falls below the manufacturer’s specifications or when the flow of oil is restricted, there will not be enough fuel to lubricate the bearing surfaces, including the camshaft. If the camshaft is lacking sufficient oil pressure, it will not only wear out but may also cause other parts of the engine to malfunction.
Bending or cracking due to excess stress is also a common cause of camshaft failure. High-performance engines tend to exert excessive mechanical stress on the camshaft, leading to cracking or breaking in a variety of ways. The causes of excess stress may include inadequate maintenance, over-revving of the engine, high engine temperatures, and using the engine above its designed capacity.
Lastly, the timing chain can be a significant factor leading to camshaft failure. Timing chain tensioners wear out over time, resulting in an ineffective grip on the chain. As a result, the chain may falter or become loose, putting additional strain on the camshaft’s bearing surface, and can lead to wear or damage.
Additionally, if a timing chain fails or snaps while the engine is in use, the camshaft can incur significant damage.
Camshaft failure can occur due to various reasons. Understanding the factors that contribute to camshaft failure and regularly maintaining your engine by changing oil filters and using high-quality oil can help prevent performance issues and extend the life of your engine.

The camshaft is responsible for opening and closing the engine valves at the correct time, allowing the proper amount of air and fuel to enter the combustion chamber, and helping to create power and torque.
As the camshaft rotates, the lobes on the camshaft push against the lifters, which then push against the pushrods or rocker arms. These pushrods or rocker arms then open and close the valves. However, over time, the constant friction and pressure on the camshaft can cause it to wear out.
The main cause of camshaft wear is insufficient lubrication. If there is insufficient or poor quality engine oil in the engine, the camshaft will not receive the proper amount of lubrication, leading to excessive friction and wear. Additionally, debris or dirt in the oil can also cause damage to the camshaft surface.
Other factors that can lead to camshaft wear include over-revving the engine, driving in extreme conditions, and neglecting regular engine maintenance. Symptoms of a worn camshaft include a loss of power and performance, poor fuel efficiency, engine misfires, and unusual engine noises.
If a camshaft is worn out, it will need to be replaced or repaired. In some cases, a camshaft may be reground or reprofiled to restore its original shape and surface. However, in most cases, a worn camshaft will need to be completely replaced to ensure proper engine performance and longevity.
A camshaft can definitely be worn out over time due to insufficient lubrication, over-revving, harsh driving conditions, and a lack of proper maintenance. If you suspect that your camshaft is worn out, it’s important to address the issue promptly to avoid further engine damage and ensure optimal engine performance.
Can a worn camshaft be repaired?
Yes, a worn camshaft can be repaired. The process involves manually checking the wear, performing a line bore, and then grinding the journals to the original specification. The worn journals are then ground down to the original size and crankshaft bearings are fitted for a perfect seal.
For high mileage or heavy-duty engines, a hard chroming process may be necessary in order to increase the life span and strength of the camshaft. Another option that is becoming increasingly popular is camshaft reconditioning.
This process involves polishing the camshaft to remove surface imperfections and restore it to its original size. Additionally, new parts may be used to replace any parts that are too damaged to be repaired.
Once the camshaft is reconditioned and all the parts are fitted, the camshaft is ready to be re-installed in the engine.
What type of failure is considered on camshaft?
A camshaft is an essential component in an internal combustion engine that serves to control the opening and closing of the engine’s valves. It’s a rotating component with a series of lobes, which press against the valve lifters, pushing them up and down and opening and closing the valves. In this way, the camshaft controls the flow of fuel and air into the engine and the expulsion of exhaust gases.
There are several types of failures that are common on a camshaft. The most common is wear, which occurs over time due to the constant contact between the camshaft lobes and the valve lifters. As the lobes wear down, they become rounded, reducing the lift and duration of the valves. This can result in a loss of power and efficiency, and can eventually lead to mechanical failure.
Another type of failure that can occur on a camshaft is a crack or fracture. This can be caused by a variety of factors, including improper installation, material defects, or excessive stress on the shaft. In some cases, a crack or fracture may be visible on the surface of the shaft, while in others it may be hidden and difficult to detect.
Additionally, a camshaft can suffer from misalignment, where the camshaft and valve lifters are not properly aligned, causing excessive wear and damage over time. This can be caused by improper installation, damage to the engine block, or other factors.
To prevent camshaft failure, it’s important to use high-quality components and to perform regular maintenance on the engine. This includes regularly changing the oil, checking the valve clearances, and ensuring that all components are properly aligned and adjusted. In the event of a failure, it’s important to have the engine inspected by a qualified mechanic to determine the cause and to take appropriate measures to prevent future failures.
Does a cam add horsepower?
A camshaft can add horsepower to an engine when it is designed and installed correctly. The camshaft is responsible for opening and closing the engine’s valves, which allows fuel and air to enter the combustion chamber and exhaust gases to exit. A performance camshaft is designed to have longer duration, lift, and overlap than a stock camshaft, which means the valves stay open longer and allow more fuel and air to enter the combustion chamber.
Additionally, a performance camshaft can increase the engine’s overall power band. A high-lift camshaft will provide more power at high RPMs, whereas a camshaft with increased duration will provide more power throughout the entire RPM range. However, it is important to note that simply installing a performance camshaft will not provide significant gains in horsepower unless the rest of the engine is also upgraded to support the additional power.
In order to achieve the full potential of a performance camshaft, other modifications such as upgraded cylinder heads, intake manifold, exhaust system, and tuning may be necessary. Additionally, the engine’s compression ratio and fuel delivery system must be taken into consideration when choosing a camshaft, as these factors will affect the overall performance and reliability of the engine.
Therefore, while a camshaft can add horsepower, it is only one component of a larger system and must be carefully selected and installed in order to achieve the desired results.
Does camming a car make it faster?
In general, camming a car can make it faster, but it depends on several factors. Camming refers to modifying the camshaft in the engine, which can affect the engine’s performance. The camshaft is responsible for opening and closing the valves in the engine, which is critical to the fuel combustion process that powers the car.
When you change the camshaft, you can change the timing and duration of the valve openings, which can affect the amount of fuel and air that enters the engine. In turn, this can change the power and torque output of the engine. A performance camshaft can increase the lift and duration of the valve openings, which will allow more fuel and air to enter the engine and increase power output.
However, there are some limitations to camming a car. First, the car’s engine needs to be able to handle the increased lift and duration of the valve openings. Otherwise, the engine may fail to produce more power, or it may even suffer damage. Additionally, other components of the car, such as the transmission and the drivetrain, may also need to be upgraded to handle the increased power output.
camming a car is just one part of the equation when it comes to making a car faster. Other modifications, such as increasing the engine’s compression ratio, adding forced induction, or upgrading the exhaust system, will also play a role in determining how fast a car can go. Additionally, the car’s weight, aerodynamics, and tires will all impact its performance, so it’s important to consider these factors as well.
To summarize, camming a car can make it faster by increasing the lift and duration of the valve openings and allowing more fuel and air to enter the engine. However, the car’s engine and other components must be able to handle the increased power output, and other modifications may also be necessary to achieve maximum performance.
What does a cammed engine do?
A cammed engine is an engine that has had its camshaft modified or replaced with a more aggressive camshaft. A camshaft is responsible for controlling the opening and closing of the engine’s valves, allowing air and fuel to enter the combustion chamber and exhaust gases to exit. A camshaft with aggressive cam lobes opens and closes the valves more rapidly, allowing more air and fuel to enter the combustion chamber and exhaust gases to be expelled more quickly.
This results in increased horsepower and torque output, as well as a more aggressive exhaust note.
Cammed engines are most commonly found in performance-oriented vehicles such as muscle cars, hot rods, and drag racers. They are especially popular among enthusiasts who are looking to improve their vehicle’s power and overall performance.
