I was putting my big-block back together after a refresh. I put in a new oil pick-up tube that was a bit too deep for the pan, so I decided to push down on the tube while it was still installed in the block. The photo shows the result: I broke off a piece of iron where the pick-up tube threads into the block. Dumb mistake. I've been thinking about how I would best fix this. I'm guessing I'm gonna have to get it welded. Just wanted to see if anyone has thoughts on this. Thanks.
