It won't hurt anything but the original supply line is plugged up. If you feel like fixing it , you may take the side cover off, behind the distributor and you will see a small oil line running from the rear cam bearing to the area in the center under were the line connects. Take the line off and clean it, air pressure works well, but make sure you point it away from you, and blow it out. It is probably all blocked up.
