The rattle your describing sounds like lifter chatter. It's normal, there is no damage being done. When the engine shuts down, if the cam is holding a valve open the valve spring pushes against the lifter. The end result is the oil in the lifter seeps out and back to the oil pan. Upon start up that valve and lifter chatter until engine oil pressure refills the the lifter. My 2001 4.4 chatters occasionally and she has 126000 miles on her. It is worse when I don't drive her for several days (more time for the oil to seep out).
The only way to stop the chatter is to replace the lifters. In case your thinking of having it done, don't. You'll be wasting your money.
