How much metal do you think is usual after engine rebuild (especially after spun bearing)? Do you worry if the oil is shiny, but there are not many bigger particies inside the filter? I also found, that exhaust pipe cutter does a great job when opening oil filters and is affordable and could be used for other works.
after a full rebuild you will always find some shavings and gray oil. how much depends what you used to assemble the engine, like plain oil or assembly lube. after the very first start, idle the engine for about 15 mins and change oil and filter. i actually found bigger chunks of metal that a magnet picked up in the filter after 1000 miles, sent oil for analysis and all is good. So yes, you will find some chunks on fresh engine but there shouldnt be any gray oil say after 2 oil changes.
Thanks for the wonderful video
this was very useful thank you
Today i learned something!

Why not have a magnet handy to check out whether a particle is metal or not?
good idea
Aluminium -is a metal too
Use *Baldwin B1402* or *Baldwin B1431* instead.
