I just purchased a turbonetics stage IV turbo from a fellow GN member.The turbo had just been gone through w a new exhaust wheel and all new seals and a Garrett .63 ex. housing.After installing th turbo he noticed oil leaking from in between the center section and the ex housing.taking the turbo back to the reputable local turbo shop he went back through the turbo -while seeing nothing out of the ordinary he replaced the seals anyway.I bought the turbo still wrapped in plastic -bolted it on my car and after about 3 days noticed oil leaking in the same spot.Has anyone had similiar experiences?Something to look for?Thanx for all replies
