Default Rear Mount Oil Leak

I made a post a couple weeks ago about oil spitting out of my exhaust. I have an STS rear mount with a GT 67. I built the motor and about a week later oil not just leaked but was being spat out of the exhaust. I haven't taken the turbo off yet cause Im out of state right now, but it boggles me. I figure its either the turbo seals or the scavenge pump not doing its job. This is my first force inducted car and I don't know much about the system. Any help would be grrrrrrrrrreatly appreciated.

Either you are feeding more oil than you should (maybe needs a restrictor on the feed line), your scavenge pump isn't working or is pumping the wrong direction, you have a blockage in the drain line somewhere, you have the turbo clocked such that the drain is inefficient, or the drain runs uphill somewhere.

How can I test or know if the pump itself gave out? the return line runs right back in the motor through the oil servicing cap and I checked it with the motor running and nothing comes back, it all dumps out of the exhaust. I'll check and see if the line is clogged. Thanks for the info.

Unhook the pump from the oil lines and take it off the car, leave the wring connected. Put the pump inlet in a bucket of water and see if it is pumping when you turn the key.
