Get a can of Seafoam motor tune. Dump half the can in the oil. Start it up and let run until the noise stops. Change the oil. Dump the other half in the new oil, in the gas tank, or hang on to it for another day. If its the hydraulic lifter causing the noise the Seafoam has never let me down! If it doesn't go away you may have bigger problems.
