I saw it fixed only once . By replacing the Vanos-Gears (Puma-case)

All 4 vanoses?
Is the issue common on also untouched engines?
One thing that crossed my mind was debris from my worn crank and my oil-filter was kind a full of small particles which was not metallic. Even dough we cleaned and flushed as much as we have access to with diesel and brakecleaner before blowing it clean and fearly dry with air.
Some of this debris might pile up somewhere up to the cams and vanoses causing less oilpressure to the vanoses.
Engine rund perfectly after 3 seconds until the next day..

My car came from Belgium a year ago, you might know it, VIN PY29212 and Belgium registration 1-NKV-059..
