...and just changed out EVERYTHING myself:
-- chains, guides, tensioners
-- oil pump o-ring and front main seal
-- head gasket
-- valve cover gaskets
-- serpentine belt, pulleys and tensioner
I have the same problem -- chain noise when engine's cold. Goes away when engine warms up. Different noise than the valve lifters. I run the synthetic oil from eEuro -- Voll-Synthese 5w/40. My oil pressure light is working correctly and never comes on (other than as is normal when cranking car to start). No oil leaks at all.
So in my case, from what's on your list, I could only think that the oil pressure relief valve or some silt in the oil pan screen could be possible.
Since the noise DOES go away when the engine warms up (within minutes), is this even anything to worry about?
