The exhaust valve on No. 5 cylinder has stuck open a couple of times on my 251. Before I have to go thruogh the time of removing the head, and everything else in the way,again, does anyone have a way to remedy valves sticking? I've been told to try adding Marvel Mystery oil to the gas. Has anyone sucessfully fixed a sticking valve problem? What causes valves to stick in the first place, moisture?
Thanks, Joe
