Common turbo failure modes create much discussion between our customers and technical department. To help identify common failures in warranty situations and to provide advice on how to prevent future failures occurring, Melett has created a series of help guides.
Overspeeding is a term used when a turbo is operating well above its normal operating limits. If there are any leaks, cracks or poor seals between the compressor and the engine, the turbo will have to work much harder than it should to deliver the required air levels to the engine.
Oil is very often overlooked as a critical component, however clean filtered engine oil is a major requirement and a necessity for all turbochargers. Contamination will cause rapid wear to various components and eventually cause catastrophic failure.
Turbochargers are manufactured to precision tolerances, within 4 microns, and rotate at speeds of up to 360,000rpm. It is important that the oil in the turbocharger remains where it should, as this could lead to an insufficient oil flow to the bearing systems
Below we have highlighted the causes and the signs of oil starvation, to help you identify and prevent oil starvation from reoccurring when carrying out a repair. If the original cause of failure is not identified it is likely the same type of failure will occur on the remanufactured turbo. A lack of lubrication can result in catastrophic damage to the bearing systems which can occur within seconds of the turbocharger commencing operation.
A foreign object is simply any object that enters the turbocharger through the air inlet or exhaust inlet. When a foreign object enters the turbocharger its performance will be affected very quickly
