When a turbo goes bad...

When a turbo goes bad...
Is there a good way to tell? I just put a T3 on my Jeep Wrangler a few days ago. It was making decent boost. About 5 psi at part throttle. I have never floored it because I am waiting on a wideband. Out of nowhere, the turbo is making zero boost. There are no leaks or smoke, and no boost. I checked the discharge piping and the BOV. Is this common when a turbo is junk, or could an internal engine problem cause a no boost situation. The engine seems to run normally.
I do still hear some spooling from the turbo, but nothing like when I first installed it. The turbo was also bought used on Ebay. I found the previous owner used a regular AN fitting on the oil feed with no restrictor.
Thanks,
Rob

This is the turbo I have. You might notice where the cheap Ebay oil feed line has a small kink right at the turbo. I wonder if I starved it and screwed the bearings up.
Could oil build-up in the compressor cause something like this? I have a line going from the valve cover right to the turbo inlet. I should put a seperator in the line I guess.
