Too deep of a clatter to be a lifter IMO, could be wrist pin. Intensity seems to change with load during revving where a lifter is more constant volume since valve spring/lifter load doesn't change with speed that much. Does it go away when the engine gets to temp?

That was with the engine warm...I started it this morning cold, couldnt hear it.
Did you have any top end play in the vavle train. I pulled the covers and everything seems to be nice and tight but that doesn't mean a lifter didnt collapse
Ok took it apart and top end looked good. I then drained oil and cut filter, only to find copper pieces in the filter. going to have it rebuilt as I think this is probably bearing failure somewhere down low.
