my header
I drive a 1982 rx7, and I have a little problem on my hands. My header has a hole in it. I don't really have the cash to buy a new one right now, so is theee any way I can patch the hole for now?

Its pretty bad. I don't think it can be welded. Especially because the hole is between the two pipes. I was told I could get this high temp putty stuff, and put it over the hole, then put a piece of metal over the putty, then hold it all down with hose clamps. Could that possibly work?

honestly, I have very little faith/trust in epoxies in many applications where I see them used with these cars, and with the heat of the exhaust of rotary gases, i'm even more skeptical that such a thing would work long term.
personally, if you're going to have to put a piece of metal over it anyway, then why not skip the putty and just have an exhaust shop cut and shape a "patch" (for lack of a better term) and just weld it to your header. would seem more reliable to, at least, to me.

I thought about that, but I don't think its possible to weld because the hole is in between the two pipes and there is probably a little less than a centimeter of room to work with.

I can't believe I wrote that. it was supposed to say "with the heat of the rotary's exhaust."

You'd be surprised what an experienced welder could fix. Maybe it can be welded from inside by access through the collector? Without pictures we're just guessing.
No epoxy of any kind will do the job for more than a few minutes.
