Renault Megane emitting lots of black smoke

I have a problem with my 2003 Renault Megane. It consumes too much engine oil and there is also a lot of black smoke. What could the problem be?

One possible reason is a failed turbo bearing oil seal so the engine oil is getting into the engine and being burned by it. Another possibility is failed valve stem oil seals.
