Check the oil pressure with a mechanical gauge-could be an oil pump issue with pressure relief valve/engine bearings

soudns like tis not a faulty with the sensor or sending unit.

sounds like something is bad with the pressure and since it is runnign rough i WOULD STOP RUNNING IT ASAP UNTILL YOU TAKE A LOOK AT THE OIL PUMP.

normally if the guage is bad it wont mkae loud noise such as you are observing.
