loktight on exhuast mani??

[jmv]

So, I seem to keep losing exhuast manifold heatshield bolts. I've replaced 2 already at one point, and periodically try to check them to keep them tight, but another one has gone missing. I was just curious if a little bit of loktight would work well. I don't know if loktight can work for those extreme temps, and i also don't want to have any problems trying to get the bolts of if and when i need to remove the heatshield.

FWIW some people have said they would lose a particular bolt b/c of a crack (my far right bolt seems the most common), but my mani doesn't appear to have any cracks, just from pulling the heatshield halfway off and doing a visual check.

the vibrations cause the screws to come loose. i constantly lose bolts from the heat shield no matter how tight they are.

I always lost screws until I just removed the heat shield. I can't see why the locktite wouldn't work well there.
