What is the engine ticking noise?
As you give very little information as to make, model, engine size or year, and exactly when it is ticking, this is just an educated guess. Normally this is valve noise caused by valve clearance issues. If it has solid lifters then they need adjusting. If it has hydraulic lifters, they may be clogged and sticking. If it has hydraulic lifters try adding a can of Seafoam engine tune to a fresh oil filter change. It can be purchased at many auto parts stores. Drive the car for 500 miles and change the oil and filter again. You may have to do this more than once to remove the deposits in the lifters. If this does not work, then the valve stems or lifters are worn, and need adjustment or possible replacement.
