Took my valve cover off to see what caused all the noise under the hood yesterday (trip home on AAA flatbed).

One of my rocker arm studs broke off, and other than running rough there was a lot of nasty clattering. Not sure yet what caused it or what else may have broke. Truck was running great with 200 miles on an engine "refresh" that included installing a mild COMP cam. I drained the oil and it was perfectly clean with no metal. I am sure I'll have more surprises when I pull the head off.
