PCV valve black smoke?

Burning oil blue smoke?

These engines have a weak point with timing chains and oil contamination. Your turbo may be on its last legs.

If it is a used car, you have to go through the whole lot to find what is wrong.

Even if you replace bits here and there as you find problems, you will never know whether the car is stock on ECU and other electronic stuff.
