Rocker arm adjustment

So after my build and driving it's time to readjust the roller rocker arms because they are starting to make noise. Any special way to go about doing this? Or just do it the same as I did when I put it together the first time? Iv seen people do it with the car running and what not and was just wondering what the best way to go about doing it is.

You gots pedestal or stud mounted? Pedestal is a pain in the nuts. Stud is really easy.

If you have hydraulic lifters and the rocker arms were adjusted properly when they were installed, you should never have to adjust them.
It's solid lifters that need frequent adjustment.

I NEVER adjust hydraulic lifter equipped engines while they are running. Do it with the engine off and rotate it by hand for each cylinder.
There are tons of YT vids and all of the pushrod V8's use the same method.

Yeah I'm just going to check to see if any are loose and then do it the same way I did it when I built it. Seems like the best thing to do

The picture of the rocker arms that he posted look like stud mount.

With the motor off and the pushrod on the base of the cam lobe, tighten down the rocker arm with one hand while you are actively spinning the pushrod for that rocker arm in the other. When the pushrod gets to zero lash (you can't easily spin it anymore) go 1/4 turn further and you are done with that rocker, move onto the next one and rotate the crank accordingly to make sure each one is on the base of the cam when you do it.

Yeah that's the way I did it when I built it. Can I do it no matter the temp of the motor?

Not sure why or even how you'd do it on a hot motor by the time you got the VCs off and burned the **** out of your hands.
