smoking problem
well, for the past few months, ive been dealing with a lil smoking issue. lil puffs of blue smoke on take offs, and also when around 5k and up there apparent. well. i did a compression test just recently. 210 on every cylinder. so thats good. i have an oil restrictor on my turbo and the problem went away after that, but ive been driving it real easy since my wideband has been down.my pcv is also perfeect. 1 coming from the back of the block, the other top block exit from the stock system, and the valve cover. now. i remembered today that i had forgot to fill my rear motor mount. so, i think that my motor is doing the gansta leaning when doing hard pulls. for exp. today i changed the plugs and regapped them. car ran better. when i got back i revved the motor in from the throttle body and watch the motor shift back more. i think my turbo is at just an angle so when it sits when the motor is off or idling, it doesnt smoke and it drains perfectly/ when the motor is in upper rpms and leans back, it doesnt drain properly and smokes from the oil not draining right from the turbo. does this make sense or am i completely off. ive been trying to trouble shoot this thing for a while and it driving me absolutely insane. it did it again today and im just sick of it.

Re: smoking problem
it doesnt smoke at all when its cold? 99% of all smoke probs with turbo hondas are crank case ventillation, valve seals, or turbo seals....if it smokes when cold its def. valve seals, otherwise i would say turbo seals, or your idea is possible as well...

Re: smoking problem
no, it doesnt smoke when its cold. it does once it warms up and im driving it. i though valve stem seals too, but there was no sign of oil on any of my plugs. last i check the turbo had very lil shaft play, but a lil more then what it was when brand new.

Re: smoking problem
this what we did on a motorcyle engine were turboing at school:
Rev it so your just almost in boost, cover about 3/4 of the piping going to the compressor. The increased suction will cause it to suck oil past the seals in the turbo if this in fact the problem.
If you dont have any piping going the the turbine i wouldnt suggest you try it though, good way to end up in a permanent shocker sign.
