Has anyone ever had this happen? Yeah...maybe, but have you also NOT bent the push rod when it happened?

I got my coupe out today after a long time sitting in the garage, romped on it one good time (8k+) and I almost thought the engine let go...started running really rough and shaking, but no smoke anywhere, no leaking oil etc.

I got home and pulled the valve covers and one of the rocker studs on the driver's side snapped off down in the holes at the threads. I haven't done any serious testing but just by rolling the push rod it appears to be straight (I know I need a more scientific measurement than that) which baffles me. I usually see and hear of the push rod bending way before the stud breaks...and this was an ARP rocker stud to boot.

Anyway, I plan on getting the threads out of the hole and throwing another stud in there and firing it up to see what it sounds like. I feel pretty confident that nothing else is hurt, but I'm still crossing my fingers.

I want to measure mine. It doesn't look that tall.

I had one break a year ago, with AFR heads and matching studs (near idle sitting still in my garage). Engine ran rough just like you describe. I replaced the one stud, and have not had any issues since.
