307 HDI White Smoke

Hello Friends,
2004 Model, 1,4 HDI 307 I have.
There was a problem with traction, oil was leaking and exhausting white smoke from exhaust.
Traction problem was caused by blockage of catalytic converter, cleaned. > The heat shields on the front have changed.
The turbo lubrication hose has burst, draining oil from here, has changed.
Engine oil and filters have changed.
We spent 460 TL but exhausting white smoke from the exhaust disturbs me.
Master's what he said was that there was very little whistling sound in the turbo and if we changed it, the white smoke could be cut off.
If it wasn't cut again, the engine would land.
If you look at the turbocharger cost, it will cost me 750 TL. > Do you think it is more reasonable to make it or sell the vehicle in this form?
What are your ideas?

It causes smoke in the turbo shaft. It escapes from the turbo shaft to the cylinder. It is the most dangerous situation in diesel. the cylinder is filled with high pressure fuel, the engine quickly rushes to a high speed. It does not neglect.

First of all, thank you for the answer.
If it is a problem with circlips, what would it cost?
I am trying to decide whether to sell or have the vehicle built.

There is a price of around 300 TL, the circlip's kit will be at the cost of engine disassembly, nobody below 500 TL will enter the engine plug & nbsp;

& nbsp; Then let's try replacing a turbo first.
If the problem is not solved, we'll look ...
