Unknown Oil Burning Issue

[FourWeeks]

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. It will not smoke much at idle or when it's cold, but when it warms up and I bring it to higher RPMs or drive on the highway it will shoot out quite a bit.

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 I don't think that's the case with this one. I ran seafoam through the throttle body, then through my brake booster vacuum line. It seems to have gotten better but it might just be wishful thinking.

Any suggestions?

Did you replace the PCV valve yet?

The PCV valve still has a rattle to it so I don't think that's the issue.

[lne937s]

even so, considering how cheap it is, you may want to replace it anyway to be on the safe side.
