How much oil?
Some people being optimistic here. If I was to guess (and thats all this is because I haven't listened to the noise) id say that a piece of turbo has been in a cylinder and destroyed a ring set.
This will cause oil in exhaust, lots of oil in your new catch can and the piston to slap around in the bore (maybe causing more damage)
Like I said this is a guess. A compression test would rule this out without taking the motor apart.
