No you can get screw in studs mainly for high performance engines.
All the 289 ford engines I have worked on have hydraulic lifters and are not adjustable. However on the older ones that have pressed in rocker arm studs they have been known to back out of the head and cause problems.
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
you knock the studs out with a hammer and then you can put the new one in it will not go all the way in you use the nut to pull the stud back in all the way
Pressed steel rims were standard equipment on the Chevy Celebrity. Eurosport models included pressed steel rally wheels, they were available on standard models. Alloy wheels were available on all models.
The pushrod cup in the rocker arm is moved closer to the center (i.e. towards the rocker arm stud where the rocker arm pivots) on a 1.6 ratio rocker arm versus a 1.5 ratio rocker arm. You have to check for clearance problems where the pushrod goes through the head since it is moved slightly toward the rocker arm stud. Comp Cams makes a tool to remove material from that side of the push rod slot in the head -- the heads have to be removed to do this as it requires you to use a drill and metal shavings are going to be created. You can check this by putting the rocker arms on and setting the valve lash and then turning the engine over by hand while checking for interference between the pushrod and the slot it passes through in the head. Need to check all 16 pushrods for interference through the entire rocker arm motion by turning the engine over by hand and making sure the pushrod doesn't bind in the slot where it passes through the head. If there's going to be an interference problem it will be on the side of the pushrod toward the rocker arm stud. You should be able to check one pushrod at a time by simply turning the engine over until the rocker arm is in a position where the valve is closed, then screwing the rocker arm nut on and setting the valve at zero lash, then turning the engine over by hand while checking for interference as you slowly turn the engine over and run the valve through an open/close cycle. Repeat for all 16. To compare just do this procedure with a stock rocker arm and look at the pushrod/slot clearance in the head as you turn the engine over, and then do the same thing with your 1.6 rocker arms and you should see the difference and be able to tell if there's going to be trouble. My own advice would be to have a machine shop convert the heads from pressed in studs to screw in rocker arm studs with guide plates as a 1.6 rocker arm places more strain on the studs and pushrods and it's just a good upgrade to get rid of the pressed in studs and use screw in studs and guide plates. When a machine shop does this conversion they just drill out the original pushrod slots in the heads because the guide plate keeps the pushrod in line and the rocker arm centered on the valve and it's just makes the valvetrain much more stable and reliable. Downside is it costs money and you have to use higher quality hardened pushrods with the guide plates -- which is not a bad idea anyway.
To remove a pressed-in stud, you usually stack up a few washers and crank the stud out with an impact wrench on the nut. If the threads are completely stripped all the way down, you may have to take the head to a machine shop and have the stud drilled out and tapped for a screw-in stud.
Pull the valve covers off. loosen the rocker arms with out taking them all the way off. then you can turn the rocker arms to pull the push rods out. replace push rods, and tighten rocker arms back down and put valve covers back on
Rods and Rocker arms were the problem with my Malibu after changing lifters
men's studs fit the men's cleats and the women's studs fit the women's cleats
Take off the interior door panel, and all will become clear. There will be a rod running down to the door mechanism, and there should be two nuts, on studs. Remove the nuts, and the studs will pull out with the old handle.
First, get yourself a fertile laying hen, and convince her to nest in your rocker. When her brood hatches, you'll have all the rocker chicks you could want.
Studs are very seldom painted at all (let alone pink)
