Lifters in vehicles can begin to tick or click over an extended period of time. One of the largest factors in a ticking lifter is sludge and debris built up inside of the valve cover on top of your engine. Removing the ticking noise should take no longer than one day to complete. The materials needed for this project are available at an auto parts store.
Open the hood. Remove the oil fill cap.
Empty the entire contents of one bottle of engine oil system cleaner into the oil fill spout. Do not worry about over filling the engine. The excess oil will make sure that enough oil is washing the lifters.
Replace the oil cap. Maintain normal driving for a 12 to 24 hour period. The engine oil system cleaner is an oil-based super detergent — it will not damage the engine.
