whats with all you chevy guys having flywheel bolts coming undone?! i've never had one come out on my fords..... but anyways... antisieze works great also on exhaust bolts, as long as they're torqued right they wont rattle loose, but they can get very stuck after a long time of operation, all the expansion from the heat and any carbon buildup from the exhaust.... and you can often break the bolts off or even break your manifold....
