I found a project car I want to get, The z32 300zx TT auto I am considering buying off a friend has a slight problem with it! It is puffing a bit of white smoke. They told me they think its the Turbo... I am thinking it could be a few different possibilities, but what do you think? I think its the seal, or its a blown turbo. It is going to be my project car, so I am going to do all the repairs myself, but where would be the first place to look to find the problem? Any help would be great.
