I thought my valvetrain was having issues here lately, while in the cabin I can hear a "ticking" from time to time. It didn't get louder or keep up with RPM when I rev'd the motor which was confusing me also. BTW, its a 2000 4.0/aw4 with 164k. So I went crazy looking for it yesterday and I found it! its on the fire wall next to the accumulator, I think 2 vacuum lines connect to it but I'm not sure what to call it. Should I replace it or will it just keep ticking? I'm just glad its not my valves.
