Need help diagnosing a problem. My SR is shooting white and blue smoke out the exhaust when I'm cruising, never when I'm idling. Doesn't smell sweet at all so I don't think it's coolant, definitely oil and some vapor.

I have done a compression test with 140 across all cylinders and a leak down test showed everything was below 10%. I have replaced the valve seals and I got a used t28 to replace my turbo because I thought it was blown. Pulled off my downpipe and there is no oil so it's probably not a blown turbo.

Wtf could it possibly be???
