Oil Pòr the escape?

Hello I have a Volkswagen Caddy 1.9 TDI 105CV of 2004.
It has been a long since it smells like burned oil when the van is stop A long white smoke and smell of burnt oil pinsi which is the spray that burns, with the days increasingly smoke and decide to change the turbo.
The turbo changes to me cancels the EGR and the van goes wonderfully no longer cuts the injection and does not smoke, I think a matter arranged.
There are the few kmts, the breakdown pilot turns on, it took it to the mechanic, it turns out that the switchboard has detected that the EGR is annulled, well as the EGR limited it conscientiously and opens and closes well it takes the spit out and is running normally.
Surprise shortly to start another to see a little white smoke and the worst when stopping in a semaforo a authentic cloud that how much shame the people who burn the car, well when accelerating diminuyes and almost disappears until I stop in another traffic light,
I suppose it is when the EGR is opened effectively disconnected the tube that opens the EGR and solved nothing of smoke.
The mechanic wants to change the EGR and I doubt that it is the EGR since I have deduced the oil enters through the EGR exhaust tube inlet, if the engine burned oil would always make smoke, not only over the egr that is when I suppose I put oil by the admission.
Question Where does the Eceite enter in escape collector? Could it be an escape valve ?, or maybe the new turbo?

The oil can be put for several reasons, the first one as you say is the EGR, but it can also do it for cylinder head, valve and rings seals, now what you could do to try is to take out the EGR and where the packaging of this one you put one that you make with velmoid that is celled, which is annulled but connected so that the computer does not put into an emergency system and tests as you tell me.

The EGR function is to allow the exhaust gases to the combustion camera in order to reduce the temperature of the camera, it is not possible to pass the EGR because it only communicates the exhaust with the admission, you must first check if your engine is consuming oil, this is in the course of a week, if so you can have step through the guides of valve It emits a lot of smoke and decreases. The turbo can also be this, checking the output hose of the admission snail towards the post -fiery, if there is a step you will find oil contamination in those ducts. If there would be no oil consumption you can have problems with excess fuel, some injector that does not seal when it is closed. They are several causes.
