I would take the valve covers off, spray carb/choke cleaner on each valve stem and rotate the engine and spray to flush the guides. Do it several times until the stem/guides are clean. Do all the valves. Change engine oil when complete. Adding an additive is only a temporary fix since oil causes the problem in the first place.
