getting fed up chasing this engine noise

crank pin going bad - usually when this is going on the noise is at 35 to 40 MPH and it happens when you back the throttle off just slightly -- and the engine unloads and free wheels the motor at that speed >>>> you get a rattling in the engine at that 35 or 40 speed - wont do it at a light wont do it unless you doing what I wrote above
yes a crank pin can be another noise but yours in something your not catching - like putting on each of the pushrod tubes and feeling something hitting something
or at no load on the pushrod and valve you can pull the top of the push rod back and forth and hear it clicking
14 people make one soup will get everyone to throw up when they taste it

may have found the problem....
just pulled it apart again for the 3rd time
i was checking ring end gap and top ring was at 0.010 on the new pistons and jugs
and checked the old ones that was at 0.023
havent gotten to the other rings yet but im assuming once they got hot they were closing up even more and may be the problem oiling wise and was getting that sound at hot temps
little bit of scoring but just barely noticeable nothing i can feel with my nail
does this sound more like the problem they were getting starved of oil and getting loud? and should i get new rings or file these ones to spec and run with it?

was looking at a few things tugged, twisted and pushed and pulled on connecting rods to feel any abnormal play....
got a measurement on endplay gap between the con rod and flywheel and it was 0.27
took some pics and maybe a dumb question but ill ask is there supposed to be that much gap between the con rod wrist pin and the inside of the piston?
