Best Answer

most likely you have a collapsed valve lifter. try changing the oil and adding a high viscosity oil treatment. if problem persists, lifters, pushrod 's, rocker arms and valve springs must be removed for inspection, such as wear or a worn spring. sometimes taking of the valve covers's will reveal the source of the problem. another thing you can try is to take off spark plug wire at plug and run engine. engine will run rough, but if noise goes away, then the problem is associated with that set of valves.
