If it still goes away after the engine's warmed up I'd say it's still the manifolds unless you're 100% sure the studs haven't broken again. Iirc reading on some of the Ram truck forums, factory has issued an updated bolt/manifold design to correctly fix the problem, just within the last 2-3 years. Better late than never? :rolleyes:
Brand new studs both sides with Remflex gaskets, Not hearing the ticking in the front fender wells. The most pronounced when I am under the truck by the oil pan......it's not a rod knock. LOL...I know what those sound like. :)
