just got home with a 1955 second series 3/4 ton truck I bought today and the PO had informed me that he could not get the engine to turn over. He had towed it around and tried to use the trans to turn the motor over, no go. When I got home, I squirted some rest penetrant into each cylinder, and used a 3/4 inch drive breaker bar and pipe to move the engine by turning the crank at the balancer. It moved, but with some resistance, has a spot where it gets pretty tight!
Was thinkin there is probably a rusty spot in one of the cylinders and the rings wont slide past it?
Does anyone have any sugestions b4 I take the pan off and the head off to pull the pistons one at a time and inspect. I will most likely need to order new rod, main bearings, and new rings. WHat do you think? Brian
