What makes a car throw a rod
The tick tick tick’ing is a loose tappet usually caused by wear and tear on the rod or insufficient torque on the valve spring. Either the tappet (and any associated worn or damaged parts) will need to be replaced or if not severely damaged the valve spring can be adjusted to the recommend/required tension which will eliminate the ticking. If your car had “thrown a rod” when in reference to tappets the damage would be much more severe and in some cases the tappet will be punctured through the valve cover.
