sounds like one of the rocker arm.when they take the valve cover off they can fell which rocker arm is wore out or needs won't damage your engine !!!
WHO changed the oil? Did YOU verify that there actually is the proper amount of oil in it? Before you run it more and possibly cause damage, you might want to do that (on level ground with engine off at least 2-3 minutes).
