The crankcase ventilation gas V8 4.0 L
 

Hi guys! Sorry for my English ))
I have a problem which I cannot solve

Some time ago I started to trickle the oil from the sensors Vano's engin v8 vanos seal.jpg

And even beginning to accumulate oil in the spark plug wells.
I ordered a new original shims under the sensors Vano's new candle rings.
After a couple of months after replacing the gaskets from under the sensor Vano's (marked in picture), began to ooze oil.

I think that there is somewhere a problem with ventilatie crankcase, oil pressure under new gaskets.
Anyone faced with a similar problem? Tell me what to pay attention.

P.S. even noticed when accelerating and pressed hard on the gas pedal, the brake pedal seemed a little pressed and when the accelerator pedal is released she also returned with a click to its original position. I think it has something to do.

You might want first to check the fuel trims. If they are good, then you may just need new gaskets. Failed gaskets let oil seep into the spark plug wells, and the oil damages the coils.

"check the fuel trims"
how can it affect the pressure in the system crankcase ?

Why do you think you have that? Hint: you may not have. But if you have then the trims may be odd.
