How an I repair a tiny stress crack in my exaust manifold which is causing an exhaust leak? Temporary quick solutions? Long term will be having it welded, but just for the weekend what do I do.

Try JB weld. But if you have acess to oxy&accyl torches pre heat the area after grinding out the crack and cleaning then braze it lowest heat possible when competed post heat it bring temp down slow so as not to stress the area any more than need be.

I've not heard of a stress crack before - are you sure your manifolds aren't shot and/or suffering from freeze damage?
