Anti Seize on spark plugs?

[Jason4x4]

I have actually seen some torque specs that say not to dip head bolts in oil, because they can cause the bolt to hydro lock in the hole, and I have seen some that say to do that. but I am done in this thread, thank you.

I agree that some will say that due to the fact that if to much fluid gets in the hole, the oil can't be compressed and will not torque correctly. That is why no one rule fits all applications. Just using that as a situation where I disagree with the torque issue stated earlier.

hehe, you guys need to come work in the marine industry...

Talk about a job where you deal with galvanic corrosion, disimilar metals, etc, it's a daily thing for us...

X2 on the marine industry thing! Haha, I'm port engineer for a tug boat company and I believe each of our engine rooms have a couple industrial sized tubs of AS compound. Only drawback I could see in using anti sieze is, as someone else mentioned, changing the torque spec on threads due to lubricity.

reducing the friction on the threads would seem (to me and my non-engineer mind) to reduce the drag and allow more accurate torque readings and measurements because you dont have as much resistance? mebbe im wrong, mebbe im not, always a/s plugs...

never used any anti-sieze on anything, and have never had a problem with anything i have worked on.

just another one of those "make you feel good about your work" products on the market.

AZ doesn't count in the realm of rusty bolts. I'm sure stuff rusts, but...

Try living in a state that salts the roads and then you will have a better appreciation of anti seize.

Exactly, torque is measuring the amount of bolt stretch not the amount of resistance caused by dirty threads or any other thread resistance. That is why you should clean the threads up on any bolt and bolt hole that needs to be torqued (or not).
