Camshaft Not Spinning, If it doesn’t rotate, check for a broken distributor drive gear or worn shaft. It's always possible that they somehow got messed up and stopped letting the crankshaft spin, but it The crankshaft and Camshaft serve different engine roles: the crankshaft converts piston motion to rotation, while the camshaft controls valve timing. See "Mechanical Interference" section above. However, the role a cam bearing plays inside an Now the crank arm doesn’t rub and chain moves around as it should between rings but still more resistance than what seems normal when spinning.
