It is a little fine screen under the oil pressure sending unit. Take out the oil pressure sending unit, and fish out the screen like basket. Clean, and re-install. Since you are there may want to replace the oil pressure sending unit. This is a common problem, and this causes only fauls oil pressure readings.
