i will say that while noise in general is not normal its not abnormal for a 4.7 to have some lifter/rocker noise at cold start for a few secs.......

if your noise lasts longer then say around 30sec id be concerned....still no way to know the cause without some diag/teardown......

my honest opinion is you could buy the cheapest oil on the market in the correct weight for your engine and change the oil every 3k and be fine.....
castrol dino oil every 3000...

Went to the dealer and was told that the Dodge 3.7, 4.7, and 5.7 all have that oily goo build up problem in the oil filler tube. Its no threat to your engine and there's little to nothing we can do about it.

The good news is that means you don't have a coolant leak.
