As a diesel car owner, you certainly need to pay attention to its various components to keep them well-maintained and functioning properly. Even mistakes in car maintenance can lead to unexpected scratches on the diesel car's piston.

This condition can also cause damage or a decrease in your car's performance. Therefore, you need to know what can cause scratches on the diesel car's piston to maintain the quality of its engine.

What Are the Causes of Scratches on Diesel Car Pistons?

Diesel car pistons are certainly not immune to scratches. This condition can disrupt the power of your car's engine. This can happen in both standard and upgraded engines. Why can this happen?

Here are the causes of scratches on diesel car pistons:

1.   Late oil change

The first cause often overlooked by diesel car owners that leads to scratched diesel engine pistons is being late to change the engine oil. A delayed oil change interval can disrupt lubrication to the piston components and liner walls.

If you continue to use engine oil that has degraded in quality, it will certainly cause scratches on the diesel car's piston. This is because the piston walls and liner are not properly lubricated.

So, before this problem occurs, try to pay attention to the oil change schedule for your car.

2.       Problematic engine cooling system

The second cause is excessive heat in the diesel car engine. A problematic diesel engine cooler can cause the cylinder temperature to rise.

The friction between the piston and liner can lead to high engine temperatures, causing the piston to melt. If left unchecked, it can eventually cause scratches on the piston and liner. Therefore, it is important to regularly check the cooling system periodically.

3. Too high turbo boost

Excessively high turbo boost can also be one of the causes of scratched diesel engine pistons.

In standard engine conditions, a turbo boost exceeding 3 bar or 43 Psi can make the piston unable to withstand the pressure due to the turbo being too high. This can cause the piston to become very hot and eventually get scratched.

Therefore, as per the standard, ensure that the turbo boost of your diesel car engine is in accordance with the standard, which is only 1.6 Bar or 20 Psi.

4. Engine age

To avoid scratched diesel engine pistons, you also need to recognize the age of the engine in your car. This could be one of the causes.

Moving engine components that rub against each other over a long period certainly cause wear on your car's piston.

5. Incorrect valve adjustment

The next cause is incorrect valve adjustment. This improper adjustment can lead to various problems, such as interference between the valve and piston.

This occurs when the valve is in operation but is still adjusted, causing the valve opening to be too long. As a result, damage can occur such as bent piston rods, scratched pistons, holes, or others.

How to Maintain Diesel Engine Pistons to Prevent Damage

From the various causes that can lead to scratches and severe damage to the piston mentioned above, you can certainly be more vigilant in maintaining the pistons in your car.

  • First, make sure you regularly change the oil according to your car's oil type
  • Ensure regular engine maintenance and light servicing, starting from valve adjustments and others
  • Keep the originality of the vehicle's engine without modifying it
  • Use spare parts that meet the standards of your diesel car manufacturer

These various maintenance steps can be taken to prevent scratches on diesel engine pistons. Of course, you will incur higher costs if damage occurs and the engine needs to be overhauled.
