Stock ct-26 turbo smokes

[LordLo]

Well in the morning when it's cold, there is no smoke. But as soon as the turbo warms up, it starts pouring smoke out the exhaust. What could this be?

more information is needed. what color is the smoke? is it a lot or just a puff? does it only happen when under boost or does it just smoke?

Well it smokes the most on deceleration... but not so much when i'm boosting. It's a bluish color which is definitely oil.

This turbo is on a 5sfe, not a 7mgte and the 5sfe was rebuilt. It never smoked when it was running NA, so it has to be the turbo. The most boost the engine has seen is 5 psi.

Bad seal in the turbo maybe. Was it rebuilt before you put it on?

I talked to a guy named Steve at turbochargers.com, and he said a basic rebuild(cleaning, seals, and bearings) would be around $275. This is a Houston company, but you could probably find someone local to you for around the same price. If the turbo is the problem, that is...

Is the turbo rebuilt? If so, you need to turn it back in for warranty if it still applies.

Also, this sounds like classic turbo problems.
