Nissan Primera P12 2.2, Black smoke

Whooshing air like noise sounds like it maybe has a boost/vacuum pipe leak.Any loss of power?

I seem to have a loss of power like the car is pulling back, you hear it sucking in air the pulls back then goes again and repeats same process like turbo is going the not going if you know what I mean

Here is some pics I have taken of potential problems

The first pipe from air filter is from gearbox, i have it too and that is supposed to be, it a vent for gearbox. (it's normal)
For the second pipe, if there's oil then:
1. either the clamp is loose and need to be tightened. Loose the clamp, take the pipe off and check inside and see if there's too much oil. If it is too much then the turbo it near to fail and you have either to repair it or replace (i reconditioned it and work as new). If there's a small amount of oil then try to tighten the clamp more and see if oil come's again (try to tighten all the clamp's from turbo all the way to EGR, if it's loose you lose pressure from turbo);
2. turbo is near to fail and you have to get the car to a good mechanic that knows about turbo to see the ax from turbo and tell you how long can you runs with the car like that until you decide to recondition or replace the turbo. (when it happened to me i didn't know that much about turbo a i skipped to nr. 2 and i've reconditioned the turbo after another 5.000 km but i didn't change gears more that 3200 RPM);
3. the EGR need's to be checked via a tester to see if all position are working, there are 24 as far as i've seen on my mechanic tester after he cleanned. You need either to clean it properly or put a mechanic to do it because needs to be cleanned the hole EGR, it isn't enough just the top part. I was having too black smoke but not much and only i accelerate the car parked, in no gear, after 2.500 RPM and that after the EGR was cleanned.

Now from what you are saying in your first post about the wooshing air seems to be loose clamp/s from turbo pip's or cracked pipe. Also check the intercooler to see if there's much oil in it, if it is clean it.
