It's pretty common. When the car has been sitting awhile 99.9% of the oil drains back to the sump. Upon starting the engine it take a sec or two for the oil pump to do it's thing and send oil where it needs to go so unusual mechanical noises can result. That is why most of the engine wear occurs at cold startup. Best thing to do is use a high quality synthetic oil and drive your car often. Or it could be a loose exhaust shield you're hearing...that's fairly common too.
