Ok, so my mechanic finally put my 18g greddy turbo in my car. Everything look and ran fine, untill smoke started to come out of the turbo. Not that much, just a llitle bit and smell like burned oil. So, we're thinking that the turbo is burning oil. The turbo was used and the guy that sold it said that it ran fine. But no. My mechanic told me that I can still run it like that and just be checking the oil level like everyday or so, and once I save some money to rebuild it. So, any comments guys......................
