Default g8 aps tt rebuilt but still leaking oil through exhaust

Not sure what's going on, but my turbos were rebuilt and I still have oil going through exhaust. I have a turbowerx exa pump and it's sending oil to valve cover. Is there too much pressure in oil feed lines? Drain setup not correct? maybe my Check valve barely opening (on return line to valve cover)?
Anyone have ideas what to look for? I can't seem to win.

Do you have a turbo timer or something similar on the pump
Once the power is cut to it, the oil left in the lines will still run down into the turbo

Could also be feeding them too much, do you have restrictors in the feed lines?

Don't you have some crazy J Line coming out of your drivers side turbo? Pointed up?

If I'm remembering correctly, that's a big problem.

I am going to attempt to fix that . But oil is coming from both sides. However the J pipe passenger side put out more than the driver side (90 degree shape)

The turbowerx is on the cig lighter so it starts on accessories. I don't think my lines have restrictors either.

You have the scavenge pump tied into the cigarette lighter? That wire can't be large enough to handle the pumps current needs. You should make a dedicated electrical circuit with a relay. Trigger the relay with whatever 12v wire you choose.

You can try installing check valves in the feed lines. Don't install restrictors unless the turbo manufacture designed the turbo to run with them.

It has a relay. I mean the power source is the cig lighter wiring.
Before I started the car I heat cycled it a few times. You think that caused grave damage To the seals?
