My 2020 1500 5.7 hemi is ticking and I can't figure out what it is. The truck has 59,500 miles on it and less than 450 idle hours. There is a loud ticking noise during idle, cold and warm, and it also matches the RPMs. I took it into my local ram dealership and they replaced both exhaust manifolds as they said they were cracked. It still ticked. I then drove it around for maybe another 200 miles and took it back in and asked them to focus on the cam and lifters. They came back to me and said that one of the lifters had failed and there was damage to the camshaft lobe. They replaced the camshaft and 4 of the lifters. It still ticks! I'm thinking about replacing the spark plugs but I doubt that's the issue. Does anyone have any suggestions?
