Possibly, a misfortunate cat sleeping under the hood. This bang is probably a loose engine mounting bolt. The noise is probley from bad rod bearings once the oil pressure is up they quiet down.After it sits a long time(over night) the oil drains down and will be noisy It may last a long time just make sure the oil level is good
