Oil leak

So today I was on my way home and it is extremely cold out. Due to the weather I have been staying out of boost as much as possible. As I was getting on the highway, I heard a small pop sound and a ton of oil smoke pouring out of my exhaust. Little comes out while accelerating but ALOT comes out when I get off the accelerator. Doesn't seem to be making any weird noises but isn't boosting nearly as much as it should and I can barely hear the turbo. The idle does seem off as well and I was experenicing some serious boost cutting about a month and a half ago but again have been trying to stay out of boost due to weather. I know it can be alot of different things and I know something is broke just need help figuring out what it might be. Thank you. Here is a list of EVERYTING done to the Evo 10.

Have you looked under the hood yet? Check for obvious boost leak from popped off vacuum lines or charge pipe. Remove the turbo inlet, check the turbo for shaft play, do a boost leak test.
