When you get acquainted with the operation of the turbine, you should pay the most attention to the prevention of failures. Turbine service should not be very usual to you, because if so, then you should address the causes of the failure. When we take care of the turbine, then it reflects on better engine performance, the truck will have maximum power, it will be fast to start and even if the truck is smaller in cubic capacity, with the right turbine you will have the impression that you driving a much stronger truck.
Do not turn off the truck abruptly after a long drive
Whether you drive long or short, any sudden shutdown damages the engine, especially the turbine. When the engine shuts down abruptly after a long drive, the combustion impurities will settle on the turbine blades, which poses a risk because any foreign body inside the turbine can damage it.
So, before shutting down the engine, let it run in place for a few minutes, and be sure to increase the engine speed before shutting down, as soon as you cool the turbine enough and prevent the combustion products from accumulating and creating a problem.
Do not start the cold vehicle abruptly
Starting the cold engine should be avoided, as it may damage the engine parts. The engine works best when it reaches an optimum temperature. To achieve this, it is necessary to warm up the engine well before starting, thus preventing temperature unevenness and friction, which in the long run saves all parts of both the engine and the turbine. So you should not force the engine to high speed until it warms up, which you can achieve if you start the engine and let it run in place for a few minutes.
Don’t delay regular oil change
Very often we skip regular small service either due to lack of money or due to insufficient time. If the truck works well, there is no need to go to a mechanic, which is a huge mistake, because regular small service prolongs the life of the vehicle and saves a lot of money in the long run. Regular oil change, checking the oil and air filters as well as the exhaust system creates an optimal environment for the normal functioning of the entire system.
To work properly, the turbocharger needs a constant supply of clean oil, and to keep the turbine in top condition, you need to change the oil and oil filters regularly. Regular replacement prevents the accumulation of carbon and other pollutants that can cause damage to the interior of your turbocharger, which reduces its efficiency and causes irreparable damage over time. The turbine is the part of the engine that is most sensitive to the lack of lubrication. Damage occurs after only 3 to 5 seconds of operation without lubrication. Fully synthetic oil produces the least amount of carbon.
It is recommended to do a small service every 30,000 km and pour quality synthetic oil. Our recommendation is: do it tunap valve tuning during every other service.
Loss of engine power
The causes of loss of engine power can be different. It is most often the case that a foreign body enters the compressor and turbine side, damaging the turbo compressor. It is also possible that due to a fault in the intercooler, the intake gases do not cool down enough or the exhaust system of the turbo compressor becomes clogged, which also leads to a loss of engine power.
Valve failure, fuel system, and even engine brakes can be the cause of this turbine problem and a clear indication that the turbine is faulty.
Not receiving accelerate
The problem that is most easily noticed while driving and that bothers drivers the most is the appearance of not receiving accelerate.
This type of failure is manifested by the fact that the acceleration of the vehicle does not occur the moment the gas is pressed, but there is a certain period of time until the engine provides a sufficient amount of gas and until the turbine starts working.
Increased pressure is one of the main causes of problems with the turbine and is manifested by the loss of gas while driving. Namely, it is known that the turbocharger works by increasing the air pressure in the engine. If there are certain leaks or bad connections between the compressor and the engine, the turbocharger will have to work much harder than it should to increase air pressure. This can significantly reduce the efficiency of your turbine.
Is of any color from the exhaust indicates that your truck has a problem that requires your attention. If you notice increased black, blue or white smoke, it is a sign that there is a malfunction on your truck, and mostly these signs represent damage to the turbocharger. Black is an indication that the engine is burning too much fuel, and is generally one of the easiest faults to fix.
If the truck emits blue smoke it is a sign that engine oil combustion. Blue smoke falls into the more difficult categories of repair and in most such cases it is necessary to inspect the turbocharger, links, cylinders, pistons, etc.
When blue smoke is noticed, and you are not able to perform inspection and repair in a short time, then it is necessary to inspect and add oil as often as possible in order to prevent its disappearance and failure of moving engine parts. Since incomplete combustion of engine oil harms the environment and also makes it difficult to start and operate the engine, it is possible that other harmful effects will occur that affect the normal operation of the engine.
White smoke is one of the more complicated forms of establishing problems and it is very difficult to eliminate the main cause of the malfunction. This problem comes down to the combustion of engine oil and the most common cause is a defective turbine. White smoke can be caused by clogging of the oil drain line from the turbocharger to the crankcase or even clogging of the crankcase internal pressure relief valve.
