Hello: Can anyone direct me to info about setting valves on 3.7 engines. I have been told one must change the push rods. Thanks

Yeah, they're not adjustable. You need the factory service manual. What issues are you having?

sounds like a loose tappet one one cylinder. runs fine

Pull the valve cover and and check for a loose rocker arm, you will have to bump it over to check them all. Hopefully you do not have a worn out cam lobe caused by the lubricants that do not have the zink additive.
