So here's another one.

I was getting ready to start putting my pistons in and when I went to take the rod caps off the guy that did my machining put them on so tight I can't get them undone. Am I missing something here like a backwards thread. I was stunned so I quit for the night before I wreck something. Feels like he used an impact wrench to put them on. I even wrapped one in a towel and lightly put it in my vice and I couldn't get it to budge . Any suggestions or ideas.

It's not just one I tried a few, I'm gonna call him tomorrow.
