When idling, oil pressure drops to nothing when engine is warm. Oil pump?

Hi there,

Have the oil pressure tested with a master gauge first, don't rely on the car gauge. If oil pressure is that low, you may have worn bearings, faulty oil pump, faulty pressure relief valve, worn cam bearings. You may be up for a re build, but get the true pressure readings first.
