[QUOTE=frankie945;7233434]under boost it will smoke like a ****. If the seals are totaly out it would probably smoke at idle. Where is your oil drain going? to a spacer or upper oil pan? Because if the oil is not draing correct you will have blow by like u are describing. The line needs to be a sraight shot no bends. drain should be right above oil level in the pan.

If it is bad seals, oil leakage from the turbocharger seals can be caused from and number of conditions, below are the most common.
1.Excess engine cranks case pressure
A.due to poor crankcase ventilation like a plugged or improperly working PCV (positive crankcase ventilation) system or an open port from the intake manifold to the crankcase.
B.Excessive engine blow by due to worn engine components
2.Too small of an oil return line, preferably ¾” to 1” minimum inside diameter
3.Oil return line routing is critical, there can be no sinks/traps and oil must return above the oil level in the crankcase.
4.Blocked oil drain at turbocharger or crankcase caused by incorrectly installed oil drain gasket or excessive use of silicone gasket material protruding into the oil drain flow path.
5.Air filter restrictions (too small or dirty) will cause a restriction and contributes to excessive amount of vacuum on the compressor end seal causing oil to be drawn past the seals.

now one of my cylinders lost some compression so i know my rings where going so would that be the cause of this blow by?????

Since I got the car. Compression is good, turbos are fresh, had a tuner tell me its cause I have no back pressure, the 3.5" monster down pipes and race exhaust suposedly cause vacuum and pull oil into intake from pcv?, there is oil in the ic pipes. So that may be the cause of it, but she still has same oil level. If I drive around normal, no smoke, in boost no smoke, in boost with up shift and more boost, no smoke. Take foot off pedal and let it roll after boost, one smart car size puff of white smoke and then no smoke.
