What are tapping valves?

In: Cars & Vehicles, Plumbing [Edit categories]

Answer:

Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.
