Oil in the right exhaust

Hi everyone,
I had the rear turbo blown, so I ordered 2 CHRA cartridges from Vargas turbo.
Got them installed and everything was fine. I was expecting to see smoke out of the exhausts for some time because both were filled with oil after the initial turbo damage. This was the case the first couple of days. I had the turbos changed a couple of months ago.
Currently the left exhaust is dry (no trace of oil) however the right one is very oily. What I noticed is that after Some spirited driving i would see bluish smoke coming out of the right exhaust and smell of burning oil.
Things I tried to fix this issue:
-replaced the valve cover
-replaced the PCV
-got the rear turbo sent back to Vargas and had it opened and inpected. No issues at all with the bearings.

I am not sure what else to do. Any ideas please?
