Little head studs came out. What now?

[Powerstroke94]

Alright guys, Im in the process if replacing the head gaskets on my truck, and when I went to get the nuts off of the studs under the injector ports I was only able to remove 3 of the nuts by themselves. The other 3 had to be removed with taking the stud out with the nut still on it. I finally got the nuts off of those 3 studs and now my question is, is there a special way you have to put the studs back in? Do you just hand tighten them then put the heads back on and torque them down or what? Thanks in advance guys!!

If it were me, I would put the studs back in with lock-tite.

When installing studs I double nut the stud ( tighten nuts together) then use the top nut to tighten the stud to torque for the stud ( use lock-tite like gimpy said ) , then use 2 wrenchs on the nuts to break the nuts free from each other and remove nuts .

I agree with the double nut the stud but remove the top nut after you get the stud installed (let it sit until LocTite cures properly). After curing torque the remaining nut to specs like is supposed to be done. If you torque with two nuts in place as soon as the first nut stops you are then applying all the torque to the top nut against the bottom nut and not where you are supposed to be applying it.

But that's just my opinion YMMV.

PS. The studs do NOT get torqued down, just snugged.

Aren't you supposed to replace head studs when doing a head gasket job? Or is this just for torque to yeild stuff?

You can go to the ARP website for more info. But of course they are having Internet issues.......

Watch the height of the studs you are reinstalling. Make sure they are at the same height as the ones still in the block. Any lower and you won't have enough threads to put nuts/ washers back on. No, the studs on the multifuel don't need to be replaced after each use. Old school technology here.

I've also found that loctite works the best for sealing studs into water jackets. Especially if they are loose threads.

 

[Powerstroke94]

So should I put them in by hand first then put the nuts on and tighten it just a little bit more? Or istall the nuts to where the top nut is even with the top of the stud and then put them in?

Thread the studs in by hand and check the height compared to the other studs. You don't want to torque the stud down in a blind hole. Just snug it and use loctite. If the stud threads in too far (is lower than the other studs), just don't thread it in all the way when you install it; use loctite.

Alrighty thanks guys! It sounds like it shouldn't be a problem now. Oh and does anyone know what size the threads are on the part of the stud that goes in the block? Im going to try and get a thread chaser for them and I don't know anything about them except that they're a course thread.

 

[gimpyrobb]

You'd be money ahead by getting a tap and die set. Buying them individually will be expensive.

 

[swbradley1]

Except that thread chasers are what you are supposed to use. Tap and die sets remove material.

 

[Powerstroke94]

I found a guy that had one that fit! Now do yall know the best way to clean the block? Is a die grinder with scotch brite roloc pads ok?

 

[gimpyrobb]

Except that thread chasers are what you are supposed to use. Tap and die sets remove material.

Only if you use the wrong one.

I've use taps and dies for thread chaser many times, Yest they remove matereal, But only if 1. they are the wrong size, And most good tap and die set come with a thread pitch gauge, and 2. The threads you are cleaning are boogered up in which case you want to take JUST the bad part of the threads out.

 

[WillWagner]

Only if you use the wrong one.

Nope. Use a die on a new bolt. It removes material. Chasers should be used to clean up existing threads
