Turbocharger is a common and important component in modern automotive engines. It increases the power and torque of the engine by increasing the intake pressure. However, as the usage time increases, the turbocharger may also fail. So, how do you determine if the turbocharger is broken? This article will introduce you to five judgment methods.

1. Observe the color of the smoke: If a large amount of white or black smoke is found in the vehicle exhaust, it indicates that there may be a problem with the turbocharger. White smoke may be due to an oil leak from the turbocharger, while black smoke may be due to incomplete fuel combustion.

2. Check the turbocharger intake pipe: There are usually oil stains inside the turbocharger intake pipe. If the number of oil stains increases, it indicates that the turbocharger may have an oil leakage problem.

3. Check the turbocharger wheel blade: The turbocharger wheel blade is a very important component. If the blade is broken or worn, it will affect the working efficiency of the turbocharger, leading to insufficient power or increased noise.

4. Observe the turbocharger bearing: Damage to the turbocharger bearing usually causes a roar. It is possible to determine if there is a problem with the bearings by hearing a sound in the engine compartment while the engine is idling.

5. Check the pressure gauge reading: The turbocharger will display the working status of the turbocharger through the pressure gauge. If the pressure gauge reading is found to be low, it indicates that the pressure output of the turbocharger is insufficient.

The above methods are only a preliminary way to determine whether there is a problem with the turbocharger. If any of the above conditions are found, it is best to go to a professional car repair shop for inspection and repair in a timely manner. The price of turbochargers varies depending on brand and model, typically between several thousand yuan and tens of thousands of yuan.
