Default White Smoke Issue

I have a 2010 cx-7 grand touring AWD that is blowing thick white smoke. I've done a lot of reading on this issue (especially mazdaspeedforum, thank you btw) and im curious what route to go to fix this issue..

I have purchased the https://damondmotorsports.com/produc...tor-banjo-bolt
bolt and installed it but still getting white smoke. man i was really hoping that fixed my issue. cheap and easy, but its still smoking after install.

So im curious what my next steps should be.! I did receive a p0139 error just prior to smoke. i read that could be caused by bad turbo seals allowing oil to run down and gunk up sensor.. is this true?

I've read i can do a list of the following before replacing the turbo..

replace pcv
change oil to 5-w40
do a seafoam treatment ( what is this and why would it fix a white smoke problem)



Id rather try everything possible before i replace the turbo.


Anyone have any advice on which route i should take.

I doubt seafoam will help. Has your coolant level dropped at all?

White smoke is generally means coolant is being burned, not oil.

thanx for the replies..

the smoke looks just like the video's i've seen of a blown turbo.. like this one.. https://www.youtube.com/watch?v=c-CkSlZo31M

doesnt really smell like oil.

my water level has not changed.. it is right at the top of the radiator cap.

did compression tests on all 4 cylinders. all were around 120.

Im also going to ask this question here rather then start another thread.


I have the 2010 AWD verions of the cx7. When i replace the turbo do i have to drop/remove the transaxle??????

i've seen both answers, yes and no, but want to know from someone whose done the work before or knows for sure ..

Pull off intake, check turbo for shaft play, maybe drain fluids as well. Turbo might be toast
