Ticking 2007 5.7 Hemi

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:
