n47 engine problems solved after cold rattle smoke and timing checks

I am opening this n47 engine problems solved thread because the car had cold rattle, a little smoke and scary internet opinions. I want to separate actual chain trouble from normal old-diesel drama.
I found this related page while comparing notes: n47 engine problems solved. I wanted a practical thread before ordering parts.
Would you check cold start audio, oil history, timing chain evidence, cam/crank correlation, injector corrections, boost leaks, EGR faults, smoke color and post-repair verification before calling it solved?
