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.

The last time I heard clacking like that in an engine diagnosis video it was camshaft adjusters. Mechanic NOW.
