- -> the "wound" is right next to the oil passage (chamfering will get
-> most but not all of it). I imagine it would be difficult to evaluate
- Unless you really gouged it bad it will probably clean up at the grinder's.
The major thing it that no burrs be left which can snag a bearing, which the
grinding will take care of. The little pit that might be left will scream
"STUPID!" every time you look at it, but the truth is a little acne on the
journal won't really hurt anything. It's unsightly and undesirable, but
nothing to get your knickers in a twist over.
- BTW, always check the journals for nicks or burrs even if you just got it
back from the shop - there are many ways for a careless machinist to ding a
journal. Same for a brand new crank from GM.
