Default Mysterious (back of the block) oil leak Maybe from turbo....

i have a turbo 95 gsr. I installed the kit myself about 2 months ago but have had an oil leak ever since. I changed the oil pan gasket...that wasn't it. I looked at the oil return line....no leaks....the oil feed line by the back of the block where it goes into the brass fitting....no leaks.

After driving the car hard, if I jack it up, the bottom of the oil pan is wet with oil as well as the sway bar (behind it) and so is the A/C line running vertically (right near the turbo). There is also a drop or two of oil on the bottom of the turbo itself where the center section meets the compressor... I m totally clueless...

My last guess would be that the oil is coming out of the turbo itself. I disconnected my piping and discovered a considerable amount of oil inside the pipe. My oil return line might not be as free flowing as possible. I know that the oil return is gravity fed so it might be backing up the oil...but Im not blowing out any smoke
I DONT KNOW?!?!?!?
PLEASE tell me what you think

if you've got a lot of oil in the charge pipes sounds like ur return is a lil restrictive and caused a back up in the turbo over time this blows out the seals in the turbo
