Is this just when cold?
Disconnect vacuum pipe from vacuum pump whilst it’s making the noise....does it disappear?

Knocking is on cold and hot engine.
I will try that with vacuum pipe in morning.

The sound is same when i disconect vacuum pipe

My guess is that the mechanic who changed the timing chain fitted a part incorrectly when putting everything back together, and the cams or valve gear are hitting it.

idk and idk where to take my car for repair, here in Croatia all mechanic are clumsy
