Fully groves mains

Bob,
Some BS creeping in here. There is no mention of your crank material, but since you are talking about increased oiling, I assume it is a performance engine & using a forged steel crank. These can be Tufftrided or Nitrided, both extremely thin chemical treatments that are gone if the crank is ground undersize; some have neither treatment & are just plain ole steel...Same with cast iron crank, plain ole CI.
The steel brg shell is as hard as the f/steel or CI. It is a 'springy', hard, steel, because when you insert it, & then remove it, it springs back into shape; mild steel does not do that.
Unless you have some method of accurately checking for raised metal, as I described earlier in this thread, you would be better of not attempting this mod at home.
