Rocker arm clicking....
I have this annoying clicking and I believe its comming from a newly installed rocker arm. I can tell that it's on the driver's side, but how do I tell exactly which rocker arm it is? Thanks guys.

Find any of them that seem to be too loose and try to re-tighten.
Another thing that you don't want to think about. A friend of mine had a terrible clicking noise that sounded like a rocker arm. It turns out that the valve guide actually came out and it was traveling up and down with the valve. Obviously this made some noise.

is there a way to pinpoint which rocker arm is making the noise without playing with them all, I tried just listening, but that didn't seem to work...

You need an electronic scope to do so. Put on the headphones and point the microphone right at each rocker .. you should be able to figure out which is making the noise.
But do like said above and make sure they are all set right.

I brought a stethascope from Pep Boys cheep. It has a rod on the end. Just touch it to the rocker studs and you'll know which one is ticking. I've used this thing a lot to find noises. You'll be supprized how well it works. In a jam you can put a screwdriver to your ear and touch the stud also. It works but not as good. :)

If you just installed a new rocker arm...it should be not like the others-different color.
Adjusting all the valves on that side would not be terribly difficult if you have problems finding which on it is...

Re: Rocker arm clicking.... (tdock)
Well, I got the stethoscope from NAPA and it was easy after that, it was the arm right next to the alternator. Thanks for the help guys, it sounds soooooooooo much better now without that clicking!

Re: Rocker arm clicking.... (mn_vette)
You can also use an old mechanics trick...with the engine running, place the 'driver' end of a long screw driver on the valve cover above each rocker. Then put your ear to the 'handle' end of the screw driver. You will be able to hear the rockers clicking away.

Actually it was one of the hampsters under my hood wearing tap shoes. Those shoes were making too much noise when he was running, so I told him to wear running shoes and it'll give me more horsepower.

No one else had said this and I didn't really read anywhere wheter or not your new rockers were full rollers, but when I installed my full rollers it sounded like there was a loose one, so we pulled the covers several times. Still sounds the same, I have even had people come up to me and comment about me needing to adjust them. Honestly if you have full rollers see if you can find someone else that has them installed and listen to their engine. It should sound like you have a loose rocker too. Between the injectors, and rockers the engine in my car makes quite a bit of noise, which from everyone I have talked to and every other car I have heard with full rollers is the way it is supposed to sound. Even go listen to an LS1 car, and you can hear the rockers.
*edit* I just checked your sig more than likely if you have already adjusted your rockers the noise will not go away no matter how much you tighten or adjust. Unless there is something else wrong like the valve guide

Re: Rocker arm clicking.... (No Ordinary 91)
The Pro magnum rockers are full rollers. I probably would have thought that the noise was normal except that it was only comming from one side of the engine, and after using the mechanic's stethiscope it was quite obvious which rocker was making the noise and after a quick adjust the noise was gone. So it was just a loose rocker.
