i had my intake manifold magnafluxed, and they found extremely tiny cracks across the secondary bores. the k5 is my "budget" 4x4, and i've already gone over said budget. so, i'd like to just use some jbweld or quicksteel to seal it up from the outside, instead of dropping a bunch of $$$ on a new manifold. my friend swears it will fail in a month, but i've seen both products hold up for years in much harsher situations. is this just too ghetto? the shop confirmed that the manifold is not warped or anything.
