Popular Turbo Problems


Overspending is a term used when a turbo is operating well above its normal operating limits. This could be from modification such as ECU software, Exhaust modification and incorrectly set turbochargers.


Oil is very often overlooked as a critical component. However, clean filtered engine oil is a major requirement and a necessity for all turbochargers. The turbocharger runs off oil supply so the quality of the oil is paramount. Try to view the oil in the engine as the blood that runs through your veins.


Oil leaks can be caused by a variety of factors, the main factor being incorrect pressure within the compressor and turbine housings. If you find oil leaks on the turbocharger rather stop driving and phone an expert before the damage becomes irreparable.

Foreign Object Damage

A foreign object is simply any object that enters the turbocharger through the air inlet or exhaust inlet. This can be from small parts braking off in the exhaust manifold, most of the time we find that sometimes parts or small items are left within the charge system and result in foreign object damage.

Insufficient Lubrication

If there is a lack of lubrication within the turbocharger the consequences can be severe. The majority of turbochargers are a floating bush style and a lack of lubrication will cause excess wear and failure.


REA (Rotary Electronic Actuator) or SREA (Simple Rotary Electronic Actuator) are fitted to many variable geometry turbos and control the variable vane movement. These components are mostly manufactured from plastic. They are subjected to major heat and are prone to play and wear.
