Free Turbo Inspection, Diagnostics Best Turbos

Increasingly, car manufacturers, in order to increase the power of a smaller motor, use of the turbocharger. Thanks to them, even a car with a small engine capacity has a relatively high power and decent torque. Unfortunately, the turbochargers are not eternal. Purchasing turbocharged car on the secondary market, we have to reckon with the fact that the most likely cost of repair or replacement of the turbocharger will not miss us.

The most common reasons of turbo failure are manufacturing defects and operational users errors . But sometimes it so happens that the turbocharger fails due to overexploitation. Today we present to you the causes of failure of the turbo. Check what are the most common failure of this component. We will also see if any turbochargers can be regenerated and reconditioned.

Turbocharger failure causes
In most cases, the reason of the turbo problems are neglects of  the user from who we bought the car. The most important element is the turbo rotor, which contains the following elements: on the one hand, a turbine which is driven by exhaust gas stream, the other – the compressor conveying air into the engine cylinders. In some vehicles, the rotor may rotate at a speed of 200 000 revolutions per minute.

At this time, the turbo can heat up up to 500 degrees Celsius. Therefore, it must be sufficiently cooled and lubricated, which is responsible for the supplied pressurized oil. If immediately after the engine will screw it on high speed, the oil does not have time to spread the good parts of the turbocharger, which will, it will run dry, rubbing the rotor bearings.

Equally reckless habit is too quick off the engine. After turning the key to “0” turbo is still spinning, but no longer pump supplies oil to it. Let us remember that even a short break in the supply can cause irreversible effects. Moreover, in this situation, it is also being carbonized oil which clog the turboe and cause damage to the plain bearings.

The optimum time, we should wait before turning off the turbo engine, is 30 seconds. If you want to extend the life of our turbocharger, you should change the oil more frequently than recommended by the manufacturer. If the instructions such treatment is recommended after 16 000 mls, let’s do it at 10 000mls. With each mile driven in our oil increases the number of different types of chips and soot, which arise as a result of the work of the drive unit. Importantly, always should use oil recommended by the manufacturer.

The most common damage of the turbocharger
The most common failure is too low oil pressure or occasional lack of lubrication, which increases the friction between the rotor shaft and the bearing, causing overheating and excessive consumption of these elements. This situation often leads to rupture so overheated roller. Sometimes it happens that the turbo gets to the metal filings or other solids, which block the rotor blade bending and breaking.

Damaged rotors do not produce the correct pressure, accelerating the wear of the bearings. The variable geometry turbo comes to seizing control of the mechanism responsible for the shoulder blades. In this type of device there are also special failures levers, whereby the blades are operated at the wrong inclination. Sometimes for controlling the rotor wings is responsible vacuum actuator, which due to corrosion or other damage just stops working.

The turbos rotor shaft is sealed lubricated by the oil on both sides of the metal rings, but as time goes on, more and more oil escapes from the turbo to the intake and exhaust system. In case of irregular servicing the oil loses its properties for contamination, causing blurring of the bearing and seal degradation. turbo how work how to fix turbo how tdoes turbo work


To replace or regenerate?
In most cases, the turbocharger regeneration is possible. The choice of rotor and bearing transfusion is just a matter of finding the right specialists. The cost of regeneration depends on the degree of wear of the turbocharger. The basic package includes the exchange of such parts the bearings and seals, the price is about £200-300.
