I have a 2008 dodge charger rt with 5.7L hemi engine recently noticed that when I first star the car theres a or what sounds to be a knock coming from engine. Eventualy the knock will subside. Should there be any concerns?

Could be a valve lifter leakdown problem if it fades away when engine is fully warmed-up-to be on the save side check the oil pressure-could also mean oil pump or engine bearings
