ok i have an sr20det
w fmic fpr walboro...
i get bad gas mileage...and small muttering from time to time but not really smoke....if i put my leg in front of the exhaust...i get like specs of oil on me....
the fuel smell is strong sumtimes too....
my sr runs good boost ok....
she bogs down when rpms drop but rarely ever shuts down....
would this be the valve stem seals or the seals on the turbo....

 

what color is the smoke, and have you checked for codes?

 

its veyry mild gray smoke.
i got it..i had a bad coilpak..
that with bad oil seals in the turbo had me freakin out...
