This is typical of the M50 it seems, It's hard to say how bad your clattering is compared to most. Try finding an auto zone and getting the Lucas Oil Stabilizer (synthetic type) and try it in place of a quart next oil change, hot conditions use 15w50 synthetic if that's what you're using, Mobil1 for 15w50 or Castrol 20w50 synthetic. That pretty much eliminated the noise in my M50.
Usually after a down shift or low rpms, accelerating lightly at low rpms.
