Just 1 mile from home, everything was going well then I decided to pull into a side street to turn around because I forgot something at home. Slow speed u-turn at idle then a small click and stalled engine in 1st. I tried restarting but the starter just spun freely, like it wasn't connected to the engine. While waiting for the tow truck I found this sensor (cam or crank sensor?) was blown off the front cover. The cover is cracked along the top too and separating from the engine.
