Smoke from exhaust when turbo spools, what's going on?
When the turbo is spooling in third gear around 3k to 4.5k RPM, I am often getting a plume of gray/black smoke out the exhaust. This is accompanied by a ratcheting clicking noise...leads me to click turbo, but I don't know. It's in the shop now receiving diagnostics. Any opinions to what's the cause of this?
