There have been a number of isolated instances of issues with oil leaks between the turbocharger and the inlet manifold.
The oil is most likely to be coming from the turbocharger. Oil leakage alone does not mean that there is an issue with the turbocharger.
If the engine is allowed to idle for long periods of time, or the application has only carried out light load duties, then the turbocharger does not create much boost pressure.
This boost pressure assists the turbocharger oil seals and helps to keep the oil from entering the inlet side of the turbocharger.
Illustration 1 | g03353816 |
Typical example that shows oil film on inlet side of turbocharger |
If there is no boost pressure then oil can sometimes leak past the seals into the inlet side of the turbocharger. Refer to illustration 1.
If there is an oil leak from any of the hoses between the turbocharger and inlet manifold, and there are no other problems with the turbocharger, it does not mean that the turbocharger has an issue.
The turbocharger should not be replaced if you are only seeing oil leaking at any of the hoses between the turbocharger and the inlet manifold.
Illustration 2 | g03353823 |
Typical example that shows that oil film is dispersed as a result of 15 minutes of engine operation at full load |
To remove the oil, the application should be operated at full load for 15 minutes. The operation of the application causes the turbocharger to generate boost pressure. The generation of boost pressure will quickly disperse the oil from the turbocharger and air pipes. The generation of boost pressure will also clear any signs of oil leakage, where the oil will be burnt in the cylinder during the combustion process. Refer to illustration 2. Once completed, any external oil can be cleaned off the inlet hoses and tubes.
Note: If the application is again allowed to run at low idle for long periods of time, or the application is only carrying out light load duties, then the oil leakage will return again. This is absolutely normal.
Turbochargers that have suffered other issues will not create the correct boost pressure, may be very noisy, or may have excessive movement between the shaft and bearings. The movement can possibly cause contact between the impeller or turbine and the housing. There may also be oil leakage, but this will be excessive and will not clear when the above procedure is completed.
Oil leakage accompanied by low power may be a symptom of applications that have been allowed to run at low idle for a long time period.
