exhaust stud installation

[yadada]

Regarding exhaust studs, what do you use on the threads that go into the head? Anything?

I was putting new gaskets on and one of the exhaust studs come out of the head.

I'm putting the copper colored anti-seize on the stud nut threads.

Iron/Steel studs into aluminum heads - anti seize should do the trick. I'm unaware of different varieties - the stuff I have is silverish.

anti sieze

the silver compound from napa is the best....very high temp

I was thinking more along the lines of I don't want the stud to come out anymore. I want the stud to stay in the head when I take the nut loose. Maybe I am crazy. My father also suggested anti-seize.

I was thinking some kinda loctite. Is this nutty?

The reason you want antiseize in there is that corrosion will be greatly accelerated without it due to putting two different metals together - Aluminum + Steel = bad times.

bad times

yeah, aluminum+steel+heat=the worst of times!

[yadada]

Okay anti-sieze it is. I think the copper stuff I have is good to 2000F, that oughta do it.

hmmm, didn't think to put anything in mine. Guess that is one thing to add to the list before it is too late.

I put anti-sieze on the studs and the nut to stud surfaces, at least when you go to take it apart in a few years and the nut may have frozen to the stud, you can remove the stud and soak it in penetrating oil to free it up. I also put anti-sieze on the header to muffler and cross-over joints ( warm it up and wipe off the excess ) makes it easier to remove as well

Actually on the XJ I don't have studs. And I think that the bolts that mount the exhaust are aluminum so I might be alright.

A dissenting opinion!

Well,

When I'm putting exhaust pipes on and off, I don't want the studs to turn, I want the nuts to turn. SO I'm more inclined to use what you were thinking at the beginning, the Red Locktite for STUDS, to keep that sucker from loosening once it's tightened in place! Like you said, you were using antiseize on the nuts that hold the pipes, and that's good, but I would secure the stud into the head....JMHO! YMMV.

Yes .. RED lock tight is the way to go on exhaust studs. Get the correct length replacements ... run a tap through the holes to clean them up.... apply the lock tight and turn the studs in until the bottom out. If you don't clean out the threads in the head the studs will be difficult to bottom out.

OK, we have gone from antiseize to red locktite! I just screw in the studs and there is no reason to crank down the nuts so tight when you have crush washers.

Red LocTite on the studs going into the head and anti-sieze on the nut part of the stud. Listen to TopCat as he is pretty much the next thing closest to God.

[TopCatGr58]

Perhaps closer to "DOG"!

BwaaaHaaaHaaa! Well, because I'm almost everywhere here on channel 11, yeah, but the Omnicient/Omnipotent department. . . . hardly! There are a bunch of folks here that are just as if not even much more knowledgable, skillful, insightful than I am, ie. KenTalbot, John, Geezer, Maximan, Prom, Gnepig, DiverRay, Fredintoon, Skids, Randy, Jerry, TrBig, Pggg, AlanB, Mathh, and the list goes on!! I'm just lucky I can touch type! That's why I'm the housekeeper here! So....let's not have anymore of this deep boots kind of comments, please!

BTW, Skids, what kind of XS do you have? I haven't seen any bikes or diagrams where they have or used the crush washers for the exhaust nuts! But perhaps that would be a good way of telling when you've gotten them torqued down enough without having to use a torque wrench!
