Should have run at normal temperatures on first startup for future reference. If the rotor is not turning on engine bump, that is BAD. Like your chain is no longer connected to your camshaft kinda bad. Cam gear tightened? Tensioner installed properly, and more importantly, correctly loosened? Tensioner guide rail pin fully re-inserted? You won't know the extent of the damage or exact cause until you tear it down. But don't get down on yourself. It's the only way to learn
