The result of the air pressure test showed MY exhaust manifold is toast. I patch up one crack, and it forces the others to open. So getting the one I found at the yard welded up tomorrow either by a friend in welding classes or I'll pay for it at a muffler shop.
I stopped up all the pipe holes and ran air through. Only at the one spot is there a leak. posted where the hairline crack I found is. Any other places I should reinforce weld it like the ? arrows

I am fighting through getting my renix xj smogged and this may possibly clear a few things up.....hopefully
