Yes and they should all be changed at the same time.
BUTIf you are changing rocker arms it indicates the inside of the rest of the engine is badly worn.DIETL: I have replaced a single rocker and would again if it made sense. In the case where I replaced one, the rocker had experienced a bearing failure likely due to a defective bearing from new. All the other bearings were fine and the rockers operating well. That car is still running over 50K later with the one changed rocker.
I've personally only seen three failure modes for rocker arms. First is worn bearings in the rocker (if fitted - some model cars have no rocker bearings). Second is a worn bearing surface where the rocker contacts the valve stem. Third is a broken rocker.
It would be a very rare occurrence for all rockers to break. It would also be relatively rare to have all rocker bearings fail. This would imply a lubricant failure. In this case, I'd say that a lot more than your rockers are damaged. In the event that the valve contact surfaces are worn, I'd suspect that your cams are worn as well. The latter two are both conditions that imply significant general engine wear.

What do roller rocker arms do?
Roller rocker arms perform the same function as standard rocker arms. Mainly, they are the mechanical link between the push rod and the valves. Roller rockers are better because they have a cylindrical roller that reduces noise and friction instead of simply having a flat spot directly contacting the top of the valve.
How do you stop the valves from clicking in a 1980 Ford 100?
First you will need to check and see that you have sufficient oil pressure. Determine which side is making the noise and remove the valve cover. Start the engine and see if all the rocker arms are getting oil. look to see that the rocker arms have the same amount of travel up and down. You did not mention the engine size. The is no adjustment as these rocker tighten all the way down and are self adjusting.

How do you fix a rocker arm if it is loose or broken in your car?
Your best bet is to buy the manual. There are multiple ways of adjusting rockers and it depends on the vehicle. Your loose rocker arm may also be an indication of a bent push rod, bent valve, or worn out cam. there are 2 types of rocker arm studs pressed in and threaded in. if it is pressed i suggest buying the same size threaded stud, tapping the hole and using 2 stacked nuts screw it into the hole in the head. if its threaded just remove the old one and thread in the new one, be sure to check torque value for this application answer if a rocker arm is broken, u need to remove rocker cover the rocker arms are all on one tube bolted to the head remove the nuts that secure this tube slide as many rocker arms as need to get to broken rocker arm, off the tube replace with new rocker arm replace others that u needed to remove. sit tube with rocker arms back in place making sure that u align all rocker arms to the proper place tighten securing nuts to proper torque over tightening will break the studs then adjust rockers to specs if engine has hydraulic lifters you will not have to adjust replace rocker covers using new gaskets if the rocker ram is loose, adjust to specs if engine has hydraulic ligters, torque to specs job is done
What is a rocker?
you are probably refering to a rocker arm. In a pushrod motor the rocker are opens the valves. A rod rides on the camshaft and as the lobes on it come around the rod pushes up on the rocker are which does exactly that, rocks the same as the rocker on a rocking chair . The rod pushes up on the rocker which then pushes down on the valve, opening it.
What does a lifter in a mustang do?
Lifters in any type of vehicle do the same thing. They are oil-filled shock absorbers in a manner of speaking, that ride on the lobes of the crankshaft. The other end of them, or the upward facing ends loosely house one end of the push rods that end up at and move the rocker arms up and down when the camshaft lobe is at its highest and lowest point for that rotation. The rocker arms are mounted to the top of the heads usually found at the top of the motor under the valve covers. The rocker arms are what push the intake and exhaust valves open at the exact right time when the camshaft rotates with the cylinders, pistons, crank.

What to do about a 1987 Nissan Stanza with a loose rocker arm?
You need to remove the valve cover and check the bolts holding the rocker arm to the head. There are at least six bolts holding the rocker arm , and I dont think they would all come loose at the same time. After you remove the valve cover you may find that you have a loose or broken valve especially if you have a skip in the engine or a rattle or both.
