Hi Linda, The only way to tell for sure the amount of damage and to keep more from happening is to remove the head and look. If there is metal floating around the cylinder it could be scoring the cylinder walls or damaging valves. Not getting it looked at could lead to big repair bills down the line. Are you certain a piece of the sparkplug broke off? Ralph
