Diesel blow by, high oil consumption, why?
Welcome to Grafco Electric, your expert resource for all things related to diesel engines. In this informative article, we will delve into the topic of diesel blow by and high oil consumption, exploring the causes and providing valuable insights on how to effectively address these issues.
Understanding Diesel Blow By
Diesel blow by is a common problem that many diesel engine owners face. It refers to the escape of combustion gases from the cylinder into the crankcase, leading to increased oil consumption and reduced engine performance. This phenomenon occurs when the piston rings fail to create a proper seal, allowing pressurized gases to pass through.
There are several reasons why diesel blow by may occur:
- Worn or damaged piston rings: Over time, the piston rings can wear out or suffer damage, compromising their ability to seal the combustion gases within the cylinder.
- Cylinder glazing: Excessive idling or light-load operation can lead to the formation of glaze on the cylinder walls, preventing the piston rings from maintaining a proper seal.
- Worn cylinder bore: Continuous use can cause the cylinder bore to wear, resulting in inadequate compression and blow by.
- Improper assembly: Incorrect installation or assembly of engine components can also contribute to blow by issues.
The Effects of High Oil Consumption
High oil consumption is often associated with diesel blow by and can have detrimental effects on engine performance. Excessive oil consumption not only leads to frequent oil changes but can also result in lubrication issues, increased emissions, and reduced fuel efficiency.
Some common factors contributing to high oil consumption include:
- Piston ring wear: As mentioned earlier, worn piston rings can allow oil to be consumed during the combustion process.
- Valve stem seals: Faulty or worn valve stem seals can cause oil to leak into the combustion chamber and be burned along with the fuel.
- PCV system malfunction: A malfunctioning Positive Crankcase Ventilation (PCV) system can result in the improper disposal of oil vapors, leading to increased oil consumption.
- Engine overheating: Excessive engine temperatures can cause oil to thin out, leading to higher oil consumption.
Solutions for Diesel Blow By and High Oil Consumption
When faced with diesel blow by and high oil consumption issues, it is essential to take proactive measures to address and rectify the problems. Here are some effective solutions:
1. Regular Maintenance and Inspection
Maintaining a regular maintenance schedule is crucial to identify and address any potential issues before they escalate. Regularly inspect the piston rings, cylinder bore, and valve stem seals to ensure they are functioning optimally.
2. Piston Ring Replacement
If the piston rings are worn or damaged, replacing them with high-quality rings can significantly reduce blow by and minimize oil consumption. This is a comprehensive solution to restore engine performance and efficiency.
3. Cylinder Honing
In cases where the cylinder bore is worn, cylinder honing can help restore the proper cylinder wall texture, enabling the piston rings to create an effective seal and reducing blow by.
4. PCV System Maintenance
Regularly inspecting and maintaining the PCV system, including the valve and hoses, can prevent excessive oil consumption and ensure proper disposal of oil vapors.
5. Engine Cooling System Maintenance
Ensure your engine's cooling system is in good condition to prevent overheating. Regularly check coolant levels, replace damaged hoses, and maintain proper functioning of the radiator and water pump.
