I get a rattling sound when the engine is started, it last for second or two, then goes away when the oil pressure comes up. The oil pressure is normal, all other systems check normal. This happens when the car has set for six to eight hours. It will not make the sound again until it's park for six to eight hours.

Hi there,

The oil filter may be draining back causing the no oil pressure rattle until it picks up pressure, change the filter for a quality non drain back type and see if that helps.
