blueish black exhaust smoke?

your burning oil.

Do you have a turbo? if so you may have bad shaft seals. If you dont have a turbo you have bigger problems. Bad rings, valve guides, cracked piston/piston skirt, ect. More info on your car would help.

yeah the black is just you running rich if your boosted.

the blue either from turbo or engine. ifg you just put a turbo on proly the the turbo.

yup yup, is it ALWAYS smoking, or only at certain throttles/gear/rpm's ?

Re:blueish black exhaust smoke?
 

it's a 99 civic dx just turbo charged. the turbo was 3 months old and in perfect condition. yes it is smoking all the time and it smokes a lot when i get on it. my safc is set around -40 all across.

what is the inside diameter of the oil drain tube, and what orientation is it in.

example. is the oil drain tube pointing down off the turbo and then directly to the oil pan w/ NO upward or horizontal directions?

if the turbo is 3mo old like u said you probably have the oil drain too small... should be 1/2" ID atleast.

the oil drain i 3/4 inch and i goes down from the turbo and then it's kinda of horizontal. the turbo is so low though i was told to put the drain hole as high as possible on the pan. Should i go with a quick bend from the turbo to the pan instead of it coming down a little? Also could it be my plugs for any reason. i just ordered some zfr7f-11 ngk's will those be alright.

Re:blueish black exhaust smoke?
 

i dont know about the plugs... if you car wasnt doing that b4 u got the turbo, then i'd say turbo needs some seals..

who did u get the turbo from? they told u its 3 months old?
