If a new turbo fails shortly after installation, it is usually put down to the quality of the turbo. If it involves a reconditioned turbo, the first suspicion is an incorrect reconditioning process; in reality, however, the problem often lies elsewhere.
Turbine wheel and turbo housing
Damage often occurs on the turbine wheel. This damage is frequently caused by foreign parts entering the turbo at high speed. This could, for example, involve a (partially) broken valve which is blown into the turbo through the exhaust manifold. The result of a damaged turbine wheel is imbalance in the turbo.
Each turbo is designed and manufactured according to the engine manufacturer's specifications. Maintenance problems, engine malfunctions, or unauthorised tuning of the engine can cause the turbo to operate outside the maximum speed range. A possible consequence of this is damage to the turbine housing and/or the turbine wheel.
A worn turbo bearing may be caused by a blockage in the oil supply. This disturbs the oil film, and the metal in the turbo could then come into contact with the turbo’s rotating parts. This causes the turbo bearing to wear out and the temperature to rise sharply.
Turbo bearing damage can also be caused by an extended oil change interval or by poor maintenance. Damage can also be caused by small metal particles left behind in the oil after an engine overhaul.
In order to prevent damage to a new or reconditioned turbo, it is very important to follow the correct installation procedure. With each turbo you will therefore receive clear instructions and tips, and we also supply the right gaskets for professional installation.
