My hunch is that the oil rings are stuck and that is only because I don’t believe that stem seals could leak that fast to create the amount of smoke that is being produced. My next idea is to kill each cyl 1 at a time by disconnecting coil and injector to see if any 1 cyl smokes more.
That’s a good plan.

I am concerned (as I suspect you are) about your comment about the amount of oils sludge in the sump. Are you literally saying it was a layer a couple of inches deep? The AOS pickups are down there, I think.
