Smoke coming out of my flexpipe....turbo seal, rings, or what? check my theory?
ok usually after i boost my car would smoke a lil, and it seems as if it comes up from behind the block, like where the flexpipe section is. now im thinking my return line isnt at its best position...the oil flange on the turbo is at a slight angle, and when it drains, its like a spiral slide (u know, the ones on the playgrounds).
do you guys think that its not draining fast enough and maybe cooking the oil?
i have another problem with the car and i think this may all tie together. sometimes if i try to just drive it normal, like leaving a light the car will have a hard time moving. sometimes even sputtering...like MAJOR turbo lag and it will even be in boost (.1-.15 bar)! but if i let off the gas a lil and proceed, it starts to go like normal, in vacuum. well heres my theory to maybe why:
im thinking as i press the pedal, the oil pressure builds up in the turbo housing and with it not draining properly, the turbo has a hard time just spinning. so once i let off the throttle the pressure goes down, and turbo can spin more freely without the oil backed up. after a hard run it'll smoke because it doesnt drain quickly enough, and just cooks the oil.
feel free to tell me that im wrong because i have no idea... hehe. id love to get more info on the issues right now. ill be adjusting the drainage system soon, so it gets a better flow. but does anyone have the same issue such as this? i mean with the sputtering and car not wanting to move. thanks in advance guys. h-t always manages to help me out.
oh, sorry if im not clear, its just hard to explain. ill elaborate more if needed. just let me know

Most likely the seals in your turbo and it's leaking oil into the exhaust. Check your breather for any smoke. If your compression is good, you can pretty much say it's the turbo.

another thing that would tell you if its turbo is disconnect the downpipe and see if there is oil, if so....its your turbo. if not do a comp test, leakdown test.
