Boost Leak Inside Turbo?

After reading several posts on the forum, I built the boost leak detector that several of you recommended from the PVC End cap. I found a few rubber boots leaking and fixed that problem right away. This forum has been a serious help for some issues I've been having, but I've been unable to find a post related to the potential problem I'm having. While the system was under about 15 lbs of boost supplied by my air compressor, I heard a leak that sounded like it was inside the turbo. I could hear airflow out my tailpipe. I did verify that the wastegate was shut, and did supply air pressure to it to verify it was moving correctly, but I'm wondering if anyone else has come across this issue. Could it be leaking through the seals inside the turbo? I'm looking at eventually replacing the factory turbo eventually with the Garret Powermax 38R, but I'm hoping to get a little more life out of this one, since the aftermarket is over $1700... It's a 2001 Excursion, with 230k on it. Just installed an aFe Stage 2 Intake, MBRP turbo-back exhaust, and the Edge Evolution programmer.

gtp38r's are only like 1,200-1,300 now.
the easy seals to replace would be the intake manfiold to compressor housing oring and the compressor housing oring.
i would try those first they are the cheapest.
do you have an egt gauge? if you have high egts i would check the up pipe donut gaskets also, those are common leaks as well.
