So i did a rebuild on my 88 supra and i am reusing the turbo that came with my car. I just retorqued my head bolts and everything is running good except i can smell burning oil sometimes and when i let my car sit and warm up the ground behind my exhaust gets covered in "black dust" and i am loosing alot of oil. The reason i call it dust is because i can blow it off of my driveway. I was just wondering if this is because of a bad turbo (which there is a good chance it is bad) or it may be something else? I am using 10w-30 Non detergent oil for the break in period and i am pulling codes 42 and 52 ( knock sensor and speed sensor) The car is running great and idles smoothly and the only time it spits this "dust" is when it has sit overnight. I am doing a compression check this weekend. does it sound like the seals are bad in my turbo or maybe something else?


FYI there are no oil leaks on the motor and i have put about 650 miles on it already.
