car smoke after boost leak test ?

I did boost leak test today, and find out that my TB shaft seal leak bad. after 45 min I start the car to go work, I saw a white smoke comeing out my pipe. After few second rev, no more smoke, yes it happent before. Any ideal ? thanks

So wait, did it stop or does it still do it? If it only did it directly after the test it was probably condensation. If it does it all the time then you may have leak tested at too high psi.

WTF condensation mean ? :) . It smoke alot for like 20 second, then I drove around then it gone. I think it smoke every time I do boost leak test. it not smoke during boost leak test, only smoke after I do boost leak test.

do you hear your oil bubbling while you pressurize? How high psi are you going?

I dont heard any oil bubbling, I test it at 15psi. then it leak down to 5 psi and stay there for about 10 second.
