ZDDP or ZDTP should be either in the oil that you chose or added to the oil you chose when running any flat tappet camshaft. The level of ZDDP has been reduced in the API SM oil spec, along with the increased use of calcium detergents and dispersants resulting in failures for flat tappet camshaft applications.
