got screwed on a Turbo Z purchase and only drove the car 50miles before 4 of 6 injectors crapped out. So trying to be the bigger man i decided to fix the issue myself!...First time working this deep into a Z...when i finally got the thing back together it started popping and smoking, the smoke was bright white then turned to light brown..My first thought is blown head gasket but could it also be a "Blown" Turbo?...i have never dealt with a Turbo before so i dont know what happens when one goes bad!...
