Don't let everybody get you down. I don't think you could have damaged the crankshaft...Or the button. What could possibly happen to the button? I have re-used a head button before that was in an engine that got a piece of sand in it, and was pitted up. My world didn't end suddenly and inexplicably...
Virtually all parts on your truck are consumable, replaceable parts...If it breaks, replace it.
But next time you rebuild, or get a new engine...Do a bit of research, and break it in properly. Either the factory suggested idle through a few tanks, or the heat cycle method.
I like the heat cycle method, myself.
