Okay, I had a turbo professionally installed in my car about 2 weeks ago, but, the turbo I bought off Ebay was bad so I bought a new one (not off ebay). I took the old one off and put the new one on. I had to switch the exhaust housing from the old one to the new one because the new one didnt fit on my downpipe. Now I hooked everything back together and started it and let it run. Smoke is barrelling out of the exhaust. Figured it was just the oil burning up because it stopped after about 2 mintues. After that I took it on the road to see how it drove. I couldnt feel any boost and noticed just a HUGE cloud of smoke coming out of the exhaust that just kept coming out. On my way home my oil light and check engine light came on and my car wouldnt go above 20mph and the RPMs kept going from 600-2k. Got home, openend up the hood and see a bunch of oil below the turbo and some on the back of the car from the exhaust. I wasnt able to see the exact location of the leak. What im asking is if anybody knows exactly what sounds like is going on. Could it be because I switched the housings or the return is not on tight enough? If you can help it would be greatly appreciated. I was working on it till 11:00pm, and figured I would look at it with a couple of friends in the morning.

-Thanks

i bet one of your oil return lines got lose. other then that i cant think of anything.

did you make sure oil was flowing out of the return ?

start with the block and work your way all the way to the turbo until you find where the leak is coming from.
