GM manifold/header thread lock??
GM manifold/header thread lock?? Hey, when I took out the manifold bolts, they have some yellowish thread lock on there that seems to work well.
Does anyone know where I can get some of that stuff to use with my header bolts? I know Loctite won't hold well because of the heat, or am I wrong?

Cant say for sure you can buy it until I know for sure what it is BUT You can buy those new from most vendors on this forum and they come with the yellow chemical.......BUT along the exact same lines I am just putting headers on my car and using the NEW gm bolts, those as mentioned come with the same yellow substance, my question IS: is that yellow coating locktite or more likley some type of never seize and if it is some type of thread sealant should I, as I have always been told, use never seize with this yellow mystery substance...?
