Not sure where to apply this. I have some smoke coming out from my exhaust. The short block is about 1 1/2 years old and about 8,000 miles on it. I was told that it may be the turbo seal, pcv valve or the rings. Any ideas? I just bought a short block to build up so i have options. If its the turbo I have a fresh rebuilt GT2835 ready to go. Let me know. Thanks, Rob.
