Help! smoke exiting out the exhaust while under boost. 2.0T Fsi

So I've been struggling with this problem for a while now, had the turbo rebuilt but oil is still getting into the inlet side causing it to get sucked up into the engine and out the exhaust while on boost.

with the turbo rebuilt it only has 100 miles on it before it started smoking up again, i doubt its the turbo. now I'm leaning towards a cracked valve cover that's allowing oil into the breather valve or the EVAP recirculation tube.

i have no check engine codes so I'm lost on where this problem coming from

don't know if this info helps or if its normal but with the engine running while pulling the dipstick the engine has a ruff idle.

any help at all is appreciated

Good luck on finding an answer . Might be normal if it's light and very little smoke . Good luck

Could be the valve cover...wouldn't recommend the evap reroute as it only addresses the evap portion of the valve cover channels, and there's the pcv as well. So, pull the valve cover and check the seal of the splash plate on the inside that seals those two ports. Just replace the valve cover if not sealed well. If smoke is eliminated, then great.

My vid ( https://www.youtube.com/watch?v=t0-G5lApFvQ&t=2s ) of the same concern showed a badly sealed splash plate and I replaced the valve cover after trying an evap reroute ( https://www.youtube.com/watch?v=JUP5Lh4tonA ) ...but that didn't solve the problem as it does for some. My engine needed to be rebuilt. Did the head rebuild: [with new valve stem guides, seals, and 0.030" exhaust spring shims], a piston, rings, and rod bearings.
