After cam break in
I was thinking about a problem i had one time. I had bought a dodge truck with a 318 in it that the guy said wouldnt run. I turned it over by the crank and it would stop and get super tight in the same spot I could go all the way back around and get stuck in the same spot. So I pulled off the valve covers and sure enough it had a a bent pushrod that had punched thru the rocker. It was wedged in there good. I took out the pushrod and it rolled right over and I drove it home in 7 cylinder. When I got it home and work on it the valve was stuck I smacked it with a hammer a few times and broke it free sprayed it down with kroil put a new rocker and pushrod in it and drove it for several years. I still have that engine! When I pulled it the bored looked rough and the heads looked rougher (more rough) ? Idk! I think it got submerged in water at some point in its life!
