Oil Commission Problems

Hello to all the foristas I am quite desperate trying to repair my megane II dci. The problem is the following after repairing the turbo for third you see the mechanic tells me that the normal oil pressure in the pressure bulb taking but that at the entrance of the turbo the pressure is very low and that unfortunately it is given up and recommends that I do not handle the car until someone makes me a more detailed analysis here where to investigate and I give that I do not find any manual of the Motor Lubrication circuit K9k that is the one that is the one that is the one that is the one that is the car.
I would know if someone can guide me more omeenos what is the route that the oil does before reaching the turbo since for me it goes straight without going more than by the filter
of already many Garcias

Hi Marcobulnes, what I found in another megane (F9Q) already Tube curves ... the corner was also almost plugged ... Solution: Change the grease pipe (70 euros in the Renault) eye! The corner does not come in the spare and you will have to use the old man clean. Try to see how yours is, and yes, the oil I think does not pass through the filter, it goes from the rag of grease direct to the turbo (it seems to me a mistake, but it is like that). Pressure greased to idle 1.2 bar, at 3000 rpm: 3.5 bar.
