07 yz 450...While changing the oil, i had to force off the oil drain bolt on the starter side of the bike. i had to take the oil drain bolt with vice grips. after finishing i noticed that the bottom cover above the oil drain bolt was worn away. about a M&M size amout was worn away by the vice grips. there is also a crack in side the worn part of the cover. it appears that there is oil leaking from this crack. i am guessing it is leaking for this, or it could be from the copper crush washer. i put the old washer on the new oil drain plug bolt. is the bottom of the oil tank thin enough that i could have put a crack in it?

i put a little jb weld on the crack. after it dries i will put oil back in the bike to see if it holds. has anyone else ever seen this before? thanks
