All Eagle cranks are finished over seas, they do not finish any of them in the USA. As for issues, I could write a book of the problems we have had with there products over the last 8 years. All in all, Eagle is by far the largest, aftermarket supplier of cranks and rods. Yes, it sucks, but this stuff happens.
For the money they are a good product, but you have to check them out very carefully before use.
If you bought this crank from a well known buyer that does some volume with eagle, they could have warrantied the crankshaft for you.
Did you balance the crankshaft ? and are you running a fluid Damper ?
From the looks of your pictures this looks like a scratch, not a crack.
Did you check the sizing of the journal ?
