Chrysler offered the 318 with overhead cams instead of a single cam in the valley. They did away with the push rods and used direct connect with the rollers and the valves. Dual means MORE THAN ONE, it doesn't always mean two in the same head. The 4.7 has one cam per head unit. Tensioner noise doesn't tick, it has a totally different sound when using a stethoscope, I have worked on several crappy Dodge and Chevy engines with that very issue. The Olds 3800 was the worst. You'll hear chain noise inside the casing as well as a slapping noise. My other question to the owner is , if it is tapping as hard as it sounds why hasn't the "Knock Sensor" picked it up? IF the 4.7 even has one.
