Whats is this smoke coming from?

Valve stem seals or turbo?

Going to be hard to tell from just the smoke. I would pull the manifold and look for oil in one of the exhaust ports. Then move to the intake and check the turbo for shaft play.

The turbo is new with less then 600 miles, Little to no shaft play, and no in and out play.

I had 9 miles on my turbo.But still checked it.

Did you take the manifold off yet to see if the ports are wet?

 

[jettster91]

I have not taken the manifolds of yet, The car doesnt seem to burn oil while idling, but It stinks in the morning when i start it,

Seem to get worse if the car idles for an extended period of time?

What weight of oil are you using?

 

[jettster91]

if i let the car idle i cant seem to notice anything, Im using Mobil one 10-30, when i decelerate, somtimes i get a hint of Oil, But its real noticeable on Shifts and two step

I do have 272 cams, So Im wondering if im not pulling a whole lot of vaccum for it to do it at idle

update, I just pulled the exhaust manifold off, took a look inside the exhaust ports didnt find anything, So i pulled the turbo the rest of the way off and Noticed a little bit of oil behind the dust shield, looks like i found my problem,

Problem may have started from your previously-kinked oil drain and gotten worse from there.

What happens when the cartridge can't drain properly is the oil will be forced to pass between the sealing ring and the housing, where it burns and sticks to both parts creating a porous sealing surface. Much like a piston ring in an engine, when the sealing ring can't do it's job oil will escape into the turbine housing and exhaust will enter the turbo until the hot exhaust flow eventually dries out the turbine-side journal bearing and the turbo fails....sometimes catastrophically.

If you're able to correct an oil drain issue whether it be excessive crankcase pressure or a pinched oil drain rather quickly, you can sometimes escape without turbine sealing ring damage.

I was going to say check your oil return line mine was doing almost the same thing and my return line was kinked so that may be the problem
