Oil LEAKING out exhaust....08 STS Twin turbo
Ok guys, having an issue with my STS turbo set up.. Rear mount, 4k miles on system, 9300 miles on car, oil is pouring out only the passenger side. I have checked the check valve, it does completely shut off. I have checked the oil pump for that side and it appears to be sending the same amount back to the front as the drivers side. The oil comes POURING out at all times while running, idle and throttle. The only thing I haven't checked is trying to swap the oil pumps to see if it will cause the other side to leak. Im positive its not the check valve, it shuts off exactly as it should when I tested it. If it were a bad turbo, I believe it would just smoke under boost, not pour out during idel.... So im thinking oil pump is maybe still sending, but going bad or getting weak? Just trying to get opinions... I have contacted STS, they were great help, sent me a great trouble shooting sheet....but everything pretty much led me to believe it has to be the oil pump, without really hard evidence...anyone went through this before, would be great to make sure its the pump before I spend $ to replace it or maybe both of them??

Oil return issue. Replace the pump. At the same time, take that turbo off and clean it out or it will smoke/etc for a long time.
