Did you happen to replace the Oil feed line going to the turbo? I wonder if that line is clogged and the bearing is starving of oil. Should be a easy to check, just unbolt the line and see if there is good flow through it.
But by the sounds of it, Yes the one you just swapped in there is dead.
As for the valve cover, check your PCV valve and make sure the orange nip is still in the intake.
Hope this helps you out
