I need help with this problem. My rocker arms are rattling and there are a couple that keep coming off no matter how hard I tighten them. Is there anyone who can help me with this problem

 

What rockers? What nuts?

 

Did you use new nylon locks or did you re-use the old ones?

 

I reused the old ones, not sure what kind they are.

 

Couple of things come to mind:

1.) If you're using stock type nuts, and they're really coming loose, just get a set of replacements.

2.) If your heads have pressed-in rocker studs, it's possible the studs are pulling out. This is usually the case if the valvesprings have been upgraded to anything stiffer than factory spec.

 

I figured out what it was. The pressed in rocker studs are coming out. How do I fix that? Can I do it myself or do I have to have a shop do it?

 

you could pin them, but I'd take them off and have a shop drill and tap them for screw-in studs...

 

i'd agree. once you get to this point with the studs, forget about getting the proper torque on them.

 

Ok fellas, I have bought a screw in type stud and a tap and dye set to fix the problem. Now I need to know how to get the old pressed in stud all the way out.

 

slide hammer'll get 'em out of there but there may be a more graceful way I'm not aware of. Maybe put a nut on with a flat washer and try to gently pry from both sides.

 

just get a buncha washers and use a nut and keep tighening...thats how i did my heads

 

see I knew there was a more graceful way

 

Just make sure to use grade 8 nuts and washers, or you'll likely strip the nuts.

 

That will probably throw off you valve train geometry, on that rocker. The bottom of screw in stud is ment to sit on a milled surface. It will probably sit up too high.

Maybe someone else, who knows their stuff can verify what I believe to be correct.

 

You can use the original rocker ***** stacked up on each other along with a rocker nut to pull the studs. That's the easy part though.
Thre screw in studs should be installed by a machine shop.
Not that it's impossible to do it by yourself, but it's hard to get them aligned by hand. In addition to that, the stud boss needs to be milled flat and square to the stud.
Of course the heads need to be removed and disassembled to do that.
Look on some of the cam companies online tech pages and there's info on that.

 

you can install your own screw in studs, but you have to use the ones without the hex on them if you don't want to take the heads off to a machine shop. Pull the studs with washers or rocker *****, I usually run a die down the stud so I have a longer threaded area to pull with. There is a tool that is about $25 to help align the tap and also is useful when pulling studs, I've known people that have gotten away without using one but It's a good idea. Also remember to dump the coolant before you pull, there's coolant under the studs, use sealer or loctite when installing the new ones and a strong magnet to catch debris from tapping is a must also.
