Default Blue smoke at idle...sometimes...

Ok, so my cars been turboed for about 3 months now and this seems to happen every once in a while.
The setup is stock b18b w/about 45,000 on it, garrett t3/t4 60 trim, sfp mani, tial wg w/.8 bar spring, rc 550's, and walbro 255hp tuned on uberdata w/plx wideband blah blah blah...

sometimes at idle blue smoke will come out of the exhaust, not a terrible amount, but enough to make me worry. AFR's at idle are around 13.1. and it will only happen after i've driven the car and have it idle for about 30 seconds. once i start driving again, tho, it won't smoke anymore, even at idle. it will always only smoke just once. i'm thinking maybe it's my return line? however, it looks good to me. is there anything else that could be causing this? also, oil pressure is normal, around ~20psi or so

my gsr was doing the same exact thing. I was running it without an oil restrictor at first and I dont know if that messed up my seals or what, but mine was getting oil in the charge pipes and it had a small amount on the bottom of the compressor housing. I bought a used turbo and put it on and now the problem has gone away. So, I'm guessing your seals are leaking on your turbo. Check your charge pipes and see if there is oil in them.

Checkj your oil return. My old Drag kit would do that because my drain was at an awful angle. make sure it is not kinked or at a bad angle, a lot of times this is the problem
