I removed the egr and the tube connected to it so i could replace the egr. The only problem is that when i was cleaning the tube, no air or cleaner could go through the smaller tubes that go to the dpfe senors. i removed the hoses and air and cleaner could pass but i wasn't sure why the smaller tubes are clogged. Does the system have to be pressurized for air to pass through it?

the tubes i am talking about are the smaller ones in tis pic

There are small orifices in there and you should be able to blow air through but not very easily
