Hassle with turbos. "Turbo" was a magic word. And for the Ford Fiesta and Opel Kadett drivers who lacked such a spell there were convincing stickers or even chrome emblems with the 'TURBO' notice on it.
The neighbors read that and shuddered ...
Such an imaginary turbo naturally cannot go wrong.
A real one. With those things it is important to look for the cause of the problem, otherwise there is a good chance that the problem will reappear a few months later. Proper diagnosis of the cause of the problem is therefore a must. Replacing only the turbo is usually not the right solution. There are a few things that can happen:
Overspeeding
There are several reasons for this problem. In addition to the release of a hose or deviation from a sensor, there may also be a hindrance to the air supply. As a result of these defects, the turbo runs too fast, which can cause metal fatigue. Pieces will eventually break off.
Contaminated oil
Contaminated oil is a common problem. Often it is caused by driving too long with the same oil. Leaking injectors can also be the cause of contaminated lubrication. The result is that there is not enough lubrication and it breaks.
Lack of lubrication
Clogged pipes, a shortage of oil or a blocked oil strainer. These are the three largest causes of a lack of lubrication.
As a result, he gets too much bearing clearance and starts running. The little bit of oil that still gets into it enters the inlet and gives alarming smoke signals
