What kills a turbocharger?
Turbochargers are a fantastic way to boost your car's performance, providing increased power and efficiency. However, they are also delicate components that require proper care and maintenance. At Kevin's Autos, with years of experience in car maintenance and repair, we've seen many turbochargers fail due to preventable causes. In this article, we'll explore the common culprits behind turbocharger failure and how you can avoid them.
1. Lack of Proper Lubrication
Turbochargers operate at extremely high speeds and temperatures, making proper lubrication critical. Insufficient or poor-quality oil can lead to increased friction and wear on the turbo's moving parts, ultimately causing failure. Common reasons for lubrication issues include:
- Using the wrong type of oil for your vehicle.
- Failing to change the oil at recommended intervals.
- Oil contamination from dirt, debris, or engine wear particles.
To prevent this, always use manufacturer-recommended oil and adhere to regular oil change schedules.
2. Foreign Object Damage
Foreign objects entering the turbocharger can cause catastrophic damage to its blades. These objects can come from the air intake system or the exhaust system. Common sources include:
- Debris from a damaged air filter.
- Broken engine components, such as valve fragments.
- Loose bolts or other small parts from the engine bay.
Regularly inspecting and maintaining your air filter and intake system can help prevent foreign object damage.
3. Excessive Heat and Overheating
Turbochargers generate a lot of heat during operation, and excessive heat can lead to failure. Overheating can cause the turbo's internal components to warp or crack. Common causes of overheating include:
- Prolonged high-speed driving without proper cooldown periods.
- Blocked or restricted oil or coolant lines.
- Excessive engine tuning or modifications that push the turbo beyond its limits.
Allowing your engine to idle for a minute or two after hard driving can help cool the turbo and prevent heat-related damage.
4. Poor Installation or Maintenance
Improper installation or neglecting regular maintenance can significantly shorten a turbocharger's lifespan. Issues such as loose connections, misaligned components, or failure to replace worn parts can lead to premature failure. Always ensure that your turbocharger is installed and serviced by a qualified professional.
5. Engine Mismanagement
The turbocharger relies on the engine's proper functioning to perform optimally. Problems such as incorrect air-fuel ratios, misfires, or excessive exhaust backpressure can place undue stress on the turbo. Regular engine diagnostics and tuning are essential to keep both your engine and turbocharger in good health.
How to Extend the Life of Your Turbocharger
To keep your turbocharger running smoothly for years to come, follow these tips:
- Use high-quality oil and change it regularly.
- Inspect and replace air filters as needed.
- Allow the engine to cool down after hard driving.
- Perform regular maintenance and inspections.
- Address engine issues promptly to avoid further damage.
By taking these precautions, you can enjoy the benefits of a turbocharged engine without the worry of premature failure.

Frequently Asked Questions
What is the most common cause of turbocharger failure?
Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
What damages a turbocharger?
Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
What causes a turbo to lose boost?
Possible causes of low boost pressure can be broken hoses, contamination build-up within the turbine or compressor areas, leaking seals, damaged shaft bearings, the wastegate sticking open or operating incorrectly, a leak in the intercooler, a blocked air filter, a damaged diesel particle filter, or a damaged catalytic ...
What are most turbocharger failures caused by?
Turbo problems are caused by a variety of factors such as a lack of lubrication, oil contamination, usage outside of standard specifications, and regular wear and tear.
What is the life expectancy of a turbocharger?
Of course, the answer depends on how the truck is used, how the engine is maintained, and whether or not the engine is operating correctly, but a turbocharger on a diesel engine will usually last for at least 150,000 miles, but more often than not, the average turbo will still be functioning correctly at 200,000 miles, ...
Can clogged air filter damage a turbo?
An example of a common problem is a clogged air filter, which does not pump enough air into the cylinder or allows dirt particles to get into certain parts. This can lead to a broken or damaged turbo and/or engine block. Air filters should therefore be replaced in good time.
How do I know if my turbo is clogged?
5 Common Signs of a Failing Turbocharger
- Excessive Exhaust Smoke. If you notice excessive exhaust smoke coming from your diesel, it's definitely time to take it to a mechanic.
- Poor Acceleration or Throttle Response.
- Loud Noises Upon Startup.
- Reduced Fuel Economy.
- Check Engine Light.
What destroys a turbo?
Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination.
How do I know if my turbo is blown?
The symptoms of a damaged or failing turbo are:
- Loss of power.
- Slower, louder acceleration.
- Difficulty maintaining high speeds.
- Blue/grey smoke coming from the exhaust.
- Engine dashboard light is showing.
Can a turbo suddenly fail?
This reduction in performance can occur gradually or suddenly, depending on the severity of the turbo's issues. An increase in exhaust smoke is a tell-tale symptom of a failing turbo, with the smoke's colour indicating different problems. Blue Smoke suggests that oil is burning within the combustion chamber.
