smoking problem...

[turbo2nr]

well i have a smoking problem may be some one can try to give me some insight on what could be the problem

under 90% + throttle on boost the car lets out a constant stream of blue-ish black smoke form the exhaust, only on 90%+ throttle, i know the black is normal b/c its running rich but the blue smoke is problems...

now on cold start the car smokes white-ish color and its still apparent even after the car warms up. now after i drive the car around the block it goes away

now i check my turbo its good no shaft play its getting oil and spitting back oil to the return back to the pan. the inlet pipes and charge pipes have no residue of oil. so i dont think its the turbo..

my guess is its the piston rings not seal well under hi load and cold start... which may mean my rings are going

does do that sound correct?

It could be your piston rings or your valve stem seals... A compression test and a leak-down test will probably let you know which.

Sounds like Blow-by. your pistons rings didnt set right. how did you break in the motor?

[turbo2nr]

the motor is the stock ka with 109k on it...

i just did a comp. test i got 180 across all 4... so im leaning towards head gasket issue...

not sure tho
