Ok, I have a d16y8. I have a greddy 15g turbo, running 10lbs. Tuned by me. Been running fine for a long time. Just recently the head gasket went. I changed that, and the car ran perfect again. While it was so cold, my car wasn't heating up at all. I changed the thermostat. I put in a new oem one. The car heated up again, but once it heated up it started blowing blue smoke, and bad.
The back bumper is black, and its just all oil. My first thought was that the seals in the turbo might have went. I have not pulled the charge pipes off yet to look for oil (its abotu -10 outside here) But i quicly ran a compression check.
Its 150,180,150,180...

I just need some help. It really seems like it doesn't burn oil untill its warmed up. It also seemed to smoke really bad just under small loads. Once i went into boost, it seemed to stop. My air fuel guage isn't working. (covered in oil) and my boost gauge does not go nearly to 10lbs anymore.
Once i got on it, and it only went to 5lbs.
I am not driving the car anymore. I just need to try and figure out what is wrong.

To be honest, im so sick of this car, if anyone wants to make me an offer, take it!
