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
Remove a rocker cover and measure one.
If it's broken it will not steer.
You may have a loose rod or loose roller rocker
could be a rod bearing, a main bearing, fuel octane too low, valve rocker arm too loose, transmission filter needs changing, timing advanced too far
check for a loose connection or a broken power source. check for a loose connection or a broken power source.
No power steering fluid, broken pump, or broken lines.
If your stick shift will not move or if it will move but the car is not shifting gears, it is broken. If it feels very loose and is not catching on any gear then it is broken.
adjust the valves- the clearance between the rocker arm and the valve should be checked with a feeler gauge.
Pushes the valve open. When the pushrod lifts up one end the other end pivots down and pushes the valve down.
It is important to know the signs of a broken part in a car. Signs on a broken water pump would be water leaking from the car, a loose pulley belt and the thermostat warning light comes on.
Rocker arms dont break. Pushrods bend and lifters malfunction, but rocker arms rarely if ever go bad. A bad lifter will make an obnoxious taptaptap noise. A bent lifter will cause significant backfiring through the carb or fuel induction system.
A bad lower control arm can cause the car to shake, wander, or be hard to steer. If the arm breaks or comes loose, then you will lose control and not be able to steer the vehicle.
