Choose Your Engine Make | Turbocharger
Defects on the turbocharger mostly have one of the following causes:
If there is insufficient lubrication, the bearings will fail and the compressor and turbine wheels grind against their housings.
Contaminated oil leads to score marks on shaft journals and bearings. Oil bore holes and seals become clogged and cause insufficient oil supply.
Intrusion of foreign bodies
Foreign bodies that, for example, enter through a defective air filter, damage the turbine or compressor wheels. The resulting unbalance damages the turbocharger bearing.
Maintenance and care
Turbochargers are designed to last for the service life of the engine. Monitoring is restricted to a few periodic checks that should be performed during every engine service. One condition for achieving longevity, however, is
exact compliance with the engine manufacturer’s servicing specifications – such as oil change intervals, oil-filter system maintenance, oil-pressure checks, cleaning of all filter systems, and regular, professional filter changes.
Such causes must be eliminated before the turbocharger is replaced. If the true causes of damage or failure are not found and corrected, they will probably recur with a new turbocharger
Please do not disassemble any part of the turbocharger.
