in all honesty i dont see where the paper will help. the issue you are going to have is that if it spun a bearing most likely your crank is scarred. best backyard fix i can see in this scenario is to pull the old bearings out, install the new bearings with some thread locker or something of the sort on the backside, but not blocking the oil passage, to help hold the new bearing in place. as long as the crank isnt scarred up too bad and the rod isnt bent it should hold, but your only gonna be prolonging the inevitable, and if you dont fix it correctly there is a chance that when it DOES come apart again, it could throw a rod and then you need a whole new block, not just a crank and bearings. i cant bring myself to suggest that you sell it once you have it patched because i wouldnt be able to do that to someone. i would save some money and just buy a crank kit for it and be done with it.
