lots of smoke after pressure test
 
well i did a pressure test today on my 2.7t. no leaks :-D. put 10 psi in it first... nothing, then 15... nothing, then just to make sure we did a quick 20. and nothing. so then i start up the car about an hour later and boy have i ever seen so much smoke. drove it down the road to clear it out and im pretty sure i killed the ozone. after about 1-1.5 miles it went away.... no check engine light.... nothing, didnt even run weird. has anyone else experienced this? what im assuming is oil pushed outa the turbos and into the engine? too much psi maybe? those seals arent supposed to let oil in the motor like that.... but anyway everything seems normal now

any opinions? im sure you guys will be very helpful... and thanks again!!!

When I pressure test my car I can hear a hissing into to intake, I'm guessing there is a hole in the throttle body for air to pass through on idle? Also I hear a gurgling from the depths of the engine, which I think comes from the oil pan (it's louder with the oil filler cap off). This tells me there is a connection between the intake and oil system that gets some air flow during a leak test. I haven't been able to isolate how the air gets to the oil and I am hoping it is normal. Maybe this could cause a pressure build up in the PCV system and make oil travel to places where it doesn't usually go so freely, resulting in oil in your intake?
