I would start with having him install a manual oil pressure gauge and monitor the oil pressure when the engine start to clatter. Im thinking that there may be something wrong with the oil pressure causing the pressure to drop which can starve the top end of oil. Have them check the oil pressure while the noise is present and let me know the results and we can work from there if need be.
