So Im assuming the stud broke in between the adjuster and the rocker? Allowing the rocker to come off obviously. Does it look like it was broke off to one side or another...or does it look like it was pulled apart?
Check both contact points on the tip of the rocker, valve end as well as pushrod end. Any signs of damage?
Could be it was just a faulty stud. I cant imagine you having a clearance issue after 14,000 miles..but you never know.
