Here our engineers list some pictures of failed turbocharger parts, usually an experienced engineer can tell the reasons according to those parts.
1. Outside Impurities
Impurities, like small rocks entered the compressor house from Air Filter.
So when you install a new turbo, it’s essential to clear or replace the Air Filter.
2. Low Grade Oil
Low grade oil or fake oil, contain too much impurities. After turbo worked a period time, those small parts like Shaft and Thrust bearing will abrase with each other.
3. Turbine Shaft’s cokes
Here you can see the turbine shaft take a lot coke on it.
4. Insufficient Oil Supply
Insufficient Oil Supply will make Turbine Shaft take a little blue color.
