Loss of oil pressure in APRIO 2008

Estimated all

thanks for this forum I would like to ask the following I have an APRIO model Nissan 2008 which after half an hour or more begins to tinitine the focus of the oil this happens when brakes for example a high but when it accelerates it goes out.

Take it with my mechanic and change the oil sensor, change the oil and put a high mileage quaquer since my Aprio has 96000 kilometers, the oil filter is also changed, and we changed the oil pump for a new echo all this the fault continues, so the mechanic told me that we put an additive to the oil the bardhal 2 we put it and follow it.

But also when the oil pump was changed and a metal tap appeared to the carter, the mechanic tells me that it is part of a doll that could have been thrown away, in addition to noticed that when I am standing the engine has a vibration but when it is not and the car runs well it is not lack of power.

This fault came out that the mechanic composed my hydrahulic direction since I was running and this leak fell on the pedals the escape if I stay covered but that same day that I give it to me it was when that fault was presented, he tells me that nothing moved me.

That I will have to do to correct this problem of the A.canmano thanks for your answers.

First it is the first to measure the precion and actual oil with a preservation meter, because the meter clock could be failing and nothing more, once the results are obtained we see the following steps because if they go well, it can be an electrical and not mechanical problem.
