I was driving to the store couple days ago,and when i parked my car and was idling i noticed the smoke coming from the tailpipe.I opened the hood,and heard a loud noise.So i thought my ebay turbo crapped out,got the car home,found oil in the compressor housing and ic piping.Replaced turbo with a stock 14b.Noise and smoke still there....
Here are couple of vides that i posted on youtube to help me identify the problem.Noise starts at around 3k rpm,but seems to be better that the rpm go up.Here are the links to the vids.

Compression test and pull your valve cover and check if your valvetrain is all intact.
