My 1953 Mercury Monterey had a stuck engine. I pulled a head, unstuck a piston, and put it back together. I got it started and it had a consistent miss. I puréed the head and intake and found a bent valve. I made a video that was way too long, but what the heck, what else do you have to do right now? Enjoy!
