After inspecting the oil passages on the cranks where the rods attach I noticed 2 of them have a slightly sharp edge, the other 2 more beveled.
Saw on Guy Crofts forum somewhere that he makes sure these holes have a nice smooth beveled edge on them.
So probably a good idea to carefully round these off with a small grinding stone.
I will tape up the areas around with duct tape, and by hand with a small ball stone with oil, take off the sharp edge.
so you're going to grind the crank journal, with a grinding stone, into the crank, with it still in the engine
, for all the swarf to sit inside the crankpins waiting for you to start the engine and wreck the shells.
sorry mate but you're going too crazy.
for what you are doing now the engine needs to come out.
strip it down, do what you've got to do then CLEAN everything properly. just taping over holes or wiping out with clothes isn't good enough
sorry to be harsh but it's gone from a simple job to a far more involved one than it needs to be.
there is a reason why guy charges a lot for his rebuilds, the amopunt of work that is needed.
you're trying to achieve stuff you don't need to.
