ok so i picked up a sr motor, before i threw it in i cleaned it up and looked over it alil. when i took the valve cover off i found a rocker arm off and the chims fell..not far just right next to spring. I put them back on and cranked it alil to make sure it seemed good. I got it in today and after a while got it started. First it seemed ok but then i started hearing a tick, and it seemed to get louder. now its pretty obvous not sure if its a spun bearing...if so whats the easiest route to take if it is, i have hear that you can fix it without removing the motor but idk
