s54 engine noise after rebuild

[Nicholas1996]

Post #1 doesn't reconcile to components referenced in post #5. Was the bottom end disassembled and all components reused?

Edit: I probably mis-read. You said "I didn't rebuild" and now I assume that means someone else did.

Yes. It was rebuilt but not by me. Sorry for the consfusion.

It sounds a bit fast for a bottom end issue. Here is a video to compare where I recall the owner forgot to torque down one of the connecting rods -

Engine was idling at 1200 in the video I posted. Would a faster noise mean it’s coming from the head??

Yeah I think you're right. Definitely too fast for the bottom end.

OP can you pinpoint where the noise is coming from with a stethoscope? Metal in the oil is definitely concerning, but I'm not sure what it could be coming from besides the bearings.

Is that metal in the oil? Something is definitely wrong. I would pull the oil pan and check on the bearings.

Yeah it’s pretty sparkely

recently rebuilt started knocking on first start up. I did not rebuild the bottom end. Going to pull it out over the weekend and inspect.
