jandref321 , I don't think you are pressurizing at the right place, and this getting mislead by crankcase ventilation..
Look at this diagram:
By applying pressure *before* crancase breather, you are pushing a lot of air into crank case. The breather hose that you are reporting as leaking is not meant to hold pressure - in fact opposite. Its function is to suck crankcase gasses when vaccum gets created by turbo compressor sucking both fresh air and some crankcase gasses.
So, the proper way to pressure test the system is to seal off the very turbo entrance and route air through it.
However, that is difficult to do because of the form the turbo is. There's now way to have a clamp go over the compressor entrance like in "normal" turbos.
So, you have to come up with a contraption to introduce pressurized air right into compressor for a proper test.
