    I needed to unscrew the check valve from the AIR tubes just above the manifold/header on the '82 'Vette. I got lucky and it wasn't seized/rusted together. I now need to reinstall the check valve and am wondering if it would be advisable to put anti-seize on the threads before I do. Will the anti-seize work in a high heat environment like that? Will it help for future removal (it needs to be removed anytime one wants to remove the valve cover:mad: ) or will it make things worse? Maybe it's not as hot as I think since the check valve is fed by a rubber hose and the issue is therefore moot.

    I stuck this here rather than a specific tech forum because it really didn't fit into any category.

    Thanks in advance for your thoughts on this.

    I use anti-seize on my exhaust manifold bolts and when they get removed for whatever reason the anti-seize is still on the threads. So it looks like the anti-seize does not get burnt off.

    Can't hurt. Anti seize is commonly used on O2 sensors (run with it Dave & Mike):).

    "If it's loose, duct tape. If it's tight, WD-40!"

    For things like O2 sensors, check valves and header bolts... There are addendums to that rule:


    For something tight that you'll want to get loose in the future, anti-seize.
    For something tight that you want to stay tight, Lock Tite.
    For something loose you never want to take apart, JB Weld.


    ;)

    Thanks for the responses guys. Didn't want to go with a gut instinct and have it turn out badly. I had considered the whole header bolt thing when contemplating this path but decided, perhaps erroneously, that they didn't see the same sort of heat at the thread end.

    If you really look deep.....you'll find COPPER ANTI SEIZE.

    It'll handle higher temps and last longer overall.

    But its 4 times as expensive. But I recommend it.....

    I'd totally forgotten about copper anti seize. Oh well, I didn't have any here anyway and I really needed to get the car buttoned up again.
