The hyd tappets can sound like a hammer if bled all the way down... not just rattly..
what happened? did it start after a short drive? a long drive, an oil change?

It is a replacement secondhand engine, it is as quiet as a mouse at 1100rpm ish. It isnt water pump disconected belt but noise still there not fuel pump disconected that to as it is on gas, wondering if its cam dont think its main bearings.Nt tappets its to deep a sound if you can understand, Compared to my doka I think its down on power, but doka is on liquid gold not gas.

vibrating?

maybe knocking against something, loose tinware?

No not tinware and I don`t think it is a baffle - too deep a tone
Sounds expensive
