not really. You can get blowby in the turbo itself from high crankcase pressure, but a turbo won't cause engine blowby.
How do you blow a engine turbo.
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.
Where would you put a blow off valve on a non turbo, and what would it blow off? So the answer is no.
Black smoke can be caused when there is an improper air to fuel ratio . This can be anything from a plugged air cleaner,injector,turbo....
Yes it can cause bulbs to blow.
ofcourse they do, they blow on any engine
The whistling will be from a faulty turbo charger
Faulty O ring
yes
It is not necessary.
No
make sure you have not blow your turbo. If you did not blow the turbo you might have put a hole into the intercooler. This will cause you to use a ton of gas
