SOMETIMES IT IS CAUSED BY THE OIL USED! THE WAY YOU DESCRIBE IT SOUNDS NATURAL, BUT YOU MIGHT CHECK THE TAPPET ADJUSTMENT! ONE OR TWO MIGHT BE A FRACTION LOOSE! THIS IS EASY TO DO, BUT REQUIRES YOU TO REMOVE THE VALVE COVERS AND WIGGLE THE TAPPETS BY HAND! TOO MUCH FREE PLAY CAN CAUSE THEM TO MAKE NOISE! YOU CAN ADJUST THEM UP A LITTLE, BUT DON'T OVER TIGHTEN THEM, OR YOU CAN DAMAGE YOUR LIFTERS! CHECK YOUR LAST OIL CHANGE, AND IF NEEDED, YOU MIGHT CHANGE TO A HIGH MILEAGE SYNTHETIC OIL LIKE MOBILE ONE, IN A 10W-30! 10W-40 IS TOO THIN FOR THAT TYPE OF ENGINE!
