ive seen somewhere, possibly on "fast n loud" where when they bedded the engine in, they used a strong magnet and stuck it on the inside of the sump. it sticks it self to the sump and will collect the bedding in material, obviously you need to be careful where u stick it, so it doesnt get bashed and do damage, then run the engine in, drop the sump again and remove the magnet and all the running in material,
In my own head it seams a good idea to drop the sump after running in, to make sure there is as little as possible material left in the sump,
probably a rubbish idea, but thought id share it,,
