Turbine leaking oil: causes and solutions

The turbine is a vital component of a vehicle engine, responsible for increasing air pressure in the engine intake to improve performance.

However, when a turbine starts to leak oil, significant problems can arise. In this article, we will examine the causes of a turbine leaking oil, the warning signs and the available solutions.

Causes of Turbine Oil Leakage

1. Damaged turbine shaft seal: The turbine shaft seal prevents the oil lubricant from entering the turbine discharge section. When this seal is damaged or worn, oil can leak out.

2. Oil pressure too high: Excessively high oil pressure can cause leaks from various parts of the engine, including the turbine. This problem can result from a fault in the lubrication system.

3. Worn or damaged turbine: A worn or damaged turbine can lead to oil leaks. The pressure and heat generated by the turbine can cause damage to the seals or the structure itself.

4. Use of poor quality oil: The use of poor quality oil can contribute to oil leakage from the turbine. Low-quality oil can accelerate wear on internal engine parts.

5. Lack of maintenance: Lack of regular vehicle maintenance can lead to turbine problems, including oil leakage. Preventive maintenance is essential to avoid this type of situation.

Warning Signs

1. Excessive exhaust fumes: One of the most obvious signs of a leaking turbine oil is excessive smoke from the exhaust. The smoke may be blue or grey, indicating inefficient combustion due to oil in the combustion chamber.

2. Loss of power: An oil-leaking turbine may not be able to generate the necessary air pressure to power the engine efficiently. This will result in a significant loss of vehicle power.

3. Excessive oil consumption: If you notice excessive oil consumption between oil changes, it could indicate a turbine leak.

4. Smell of burnt oil: A persistent smell of burning oil in or around the vehicle can be a sign of an oil leak from the turbine.

5. Abnormal noises: A damaged turbine due to oil leakage may produce abnormal noises, such as whistling or hissing, during acceleration.

Solutions for Turbine Oil Leakage

1. Inspect the shaft seal: If the shaft seal is damaged, it will have to be replaced. This is a complex operation that requires the expertise of a specialised mechanic.

2. Check the oil pressure: Make sure that the vehicle's lubrication system works properly. If the oil pressure is too high, the system will have to be repaired or replaced.

3. Repair or replace the turbine: If the turbine is the cause of the oil leakage, you will have to decide whether to repair or replace it. Replacement may be necessary if the turbine is severely damaged.

4. Use high-quality oil: Make sure you use high-quality oil and observe the manufacturer's recommended oil change intervals.

5. Preventive maintenance: Regular vehicle maintenance is essential to prevent turbine problems and oil leakage. Follow the recommended maintenance schedule for your vehicle.

In conclusion, turbine oil leakage is a problem that requires prompt attention. Monitor the warning signs and consult an experienced mechanic if you suspect a turbine oil leak. Preventive maintenance and the use of high-quality oil can help prevent this situation and keep your vehicle in top condition.
