smoke under boost

[triggerx]

its a 1g, seems like it smokes under boost, and under boost only.Not quite sure what it is, it doesnt seem like its coming from my exhaust tho, its almost as if something is getting on the o2 housing? Any idea as to what could be burning off the O2 housing only under boost?
Ive got a few leaks under the car, directly under that flex part of the oil return line, as well as by my front driver side tire

Well check for shaft play in the turbo, and look at the return line mine broke and had smoke all the time but inspect the turbo.
