Last week I noticed a crack in a crankshaft counterweight:

This crank was turned 10 under and polished in 1979 and neither I nor the shop noticed it then, so I have no idea when it happened. Because of the location (and because it hasn't been a problem to this point), it doesn't worry me. Any thoughts?
