Re: valve seat crack

I could barely see it. It's not where the black mark is right, it's to the right?

Iron heads right? Just tell him to put a valve insert in there.

Yea, I still don't see it. Use MSpaint, give me a red circle.

Re: valve seat crack

That just looks like a blemish from a sharpie. Can you get a close up macro shot of it?
I can't tell if that crack goes anywhere either?

If it doesn't go anywhere, he can cut it out and press in an insert for the same valve size. Then just lap it to your valves (and cut the right seat angles) and bobs your uncle.
