Hmm, went for a drive after doing the retorque, boost was shit, could barely hear the BOV, and I was coughing up white smoke
I gave it a few revs at red lights, and it spewed a lot of white smoke... Once I got home, I checked the overflow tank, and it was a bit low (not low enough for the coolant light though). I can't seem to make it smoke white anymore, and I fixed two hoses that looked like they weren't on tight enough.
No oil in the coolant either.
I guess we'll have to see, I'm gonna let it sit for a bit then take another drive.
