A faulty turbo is indicated by pure black smoke when engine revs are above idling revs and it can also be shown by poor machine performance.
not really. You can get blowby in the turbo itself from high crankcase pressure, but a turbo won't cause engine blowby.
The whistling will be from a faulty turbo charger
Signs of turbo going out are engine power is down or engine smokin oil leaking from turbo turbine shaft seal into combustion Chamber
diing
It can be a few things, turbo seals leaking faulty crankcase valve faulty bell pan.
Faulty waste gate, improperly sized turbine housing.
Make sure the boost air isn't escaping from anywhere; for example the piping which runs from the turbo, to the intercooler, then to the engine. If any of this is split or frayed then your engine will be getting a lot less boost than it is supposed to. As well as this it could indicate a faulty turbo. Or a faulty wastegate, in which case you will need to replace the turbo unless you have an external wastegate, in which case just replace wategate
Unpredictable engine performance and pulsating lights are some of the signs of a faulty voltage regulator. A dead battery is also a symptom of a faulty voltage regulator.
Yes it will smoke a little bit from it but if it is smoking a lot then its burning something.
No it dosent but fix it ir replace because the air and fuel ration is the key to cumbustion and a faulty turbo is less air/oxygen to the fuel which means your engine wont properly burn the fuel which means you can mess up your engine bad
boost control vavles faulty
Yes, can leak oil causing blue smoke
