A few weeks ago while cruising in town I had a exhaust rocker stud break # 1 cyl. Maybe 2000 RPM at most.
Scared the doo doo out of me. Sounded and felt like the motor blew up.
Flat bed it home, pulled rocker covers, breathed a sigh of relief, slept very well that night.
1/2 hour job and back on the road the next day.
Follow previous advice and pull rocker covers. Could save you a lot of money and time.
