Anti-sieze vs Locktite
Since a lot of engine bolts break (from what I've been told) and have to be drilled out, why not use anti-sieze instead of locktite? After all, wheel lugnuts don't come loose, and they have anti-seize on them.

Why would you want to use loctite on engine bolts? Like you said, the bolts break. What happens if you can get them out after they break?

as long as you periodically check the torque of your lugs you should never have a problem, I've never had one back off. The real problem w/ lugs is when some stoner auto-shop worker puts an alloy lug on w/ a air wrench, -that has happened to me. it broke in half while I was trying to get it off (over the 250lb limit of my torque wrench). fun-fun

mochman, anti-sieze not bad on lugs, anti-sieze necessary on alloy nuts. Porsche puts anti-sieze on from the factory, they don't do that just because they have some lying around and need to use it. Without any anti-sieze on the threads the alloy nuts will SIEZE.

thats why i specifically tell guys at the tire shop, when i used go, to not use an air wrench on anything, and to torque the lugs on at 90lbs. i always tell them exactly what i want, how i want it done. i dont get **** from them, and im never disappointed, cause they followed my directions. now im luckey my dad has his own tire mounter, balance and weights in his garage, so i can just do it myself. you know, if you have the yellow or red mark on the tire wall directly out from the valve stem, your wheel will be balanced more than 90% of the time?? 
end rant....
i only use anti seize on parts that are supposed to be super tight, but must come off at a moments notice by hand.. IE fan belt/generator nut. lugs are only at 90 ft/lbs.. why the hell do i want anti-seize on there?
as far as engine parts having anti seize.. if its supposed to come out as part of regular maintenence.. yeah.. if its not supposed to come out, no.

Anti-seize is used to prevent galling. Locktight is to help keep bolts/nuts from loosening. Lugs get anti-seize becuase of the frequency they are taken on/off and the temperature and abused they are put through.

I use anti seize on anything I don't want seizing up like exhaust bolts, bell housing bolts (nothing like a tight bolt there with no space to turn a wrench and no leverage), lug nuts, etc. It will let you accurately torque down your bolts. I love that stuff and never had problems with anything backing out, because I tighten the bolts properly.

I also use anti-sieze on everything I possibly can, including spark plug threads. If you ever loosen a "dry bolt" quickly with a socket wrench, feel how hot it is once you finally get it out.
My father heard some new "rumor/speculation" that using anti-sieze might "fool" a torque wrench so that you over-torque a bolt, but neither of us believe it.
Also, I think the trick here is also not to goop on so much that it runs out of the threads on either side of the hole. And try not to get it all over everything. I have never had a bad experience with anti-seize - other than
making a mess everywhere.

anti-sieze is like the BLOB, Touch it and it is all over you. almost worse than a broken ink pen. Plus I would rather retighten a loose bolt than drill out a stuck one..jmho. Though I have never had to retighten one. IT lubes the threads. thus a tighter fit..If you dont beleive it, Try puting together a pipe fitting one with nothing, one with thread tape, one with antisieze. check out how far each one assembles. To total tightness with a wrench. Then take them apart see which one tightend farther and which loosened the easiest...
