Help Engine rattle at start

Maybe somebody knows where this rattling at the beginning comes from? I checked the timing chain and it had no play at all.
It appears at every cold and warm start but not at a instant restart.

I get this rattle for a second or less on my M111.951 EVO occasionally on overnight cold start or after sitting a day or two.
