I am in the middle of cleaning up a diff to swap into my kj for the broken one. Once I cleaned up the replacement it looks like it is oxidizing or crackling in some spots. Image
I'm still going to put her is it's better thank a broken one but kinda making me nervous.

Ship it over to my house in TX....I will run it for a while and tell you if it was good.

It looks ok to me, you can take it to a "head shop" and they can do a ultrasound on them for cheap if you want the piece of mind. But it looks ok, but Im no metal oxidation expert.

It's going in tomorrow either way. Thanks for the input. I didn't think about ultra sound.

Looks normal to me. I have seen it lots of times on other castings as well.

Common and minor casting flaws for sand cast aluminum.
