Broken rocker arm

I recently purchased a 99 forester sohc with a bad headgasket. Im fairly familiar with the ej series of engines but encountered something ive never heard of before. When removing the valve cover on the left cylinder head part of an exhaust rocker arm just dumped out. I am always very careful and patient when removing stuff so I know I didnt bump it or anything.

Now it was only one of the tabs that broke so there was still 1 exhaust valve opening. The cyl head and valves with the rocker problem are caked with carbon buildup so i know its been like this for a little while. The valves are straight and not frozen in place.

Before the teardown the car ran and drove, just leaking a little coolant out the bottom of the head. Im not sure what could have caused the rocker arm to snap. Has anyone else heard of something like this? The valve adjustments were a little tight, maybe that had something to do with it.

I ordered a new rocker from the dealer for $48 and i should be fine.

upon further inspection one of the exhaust valves is slightly bent and valve seals will be replaced. I did not find any damage to the valve guides but will be taking a closer look when i have it back to my bench.

You move pretty quickly. Are you a professional mechanic? Will you be sticking around here now?

professional mechanic? not even close, I dabble in all trades but dont consider myself a professional anything. My ability to work fast is all due to proper prep: read, take notes and rely on a decent memory to get things back together (10plus years tinkering with cars doesnt hurt either).

And yes to the last part
