    Thumbs down Holy hole

    So at the begining of summer I noticed a small hair line crack on the # 1 header. I thought it was just a thin spot in the coating. Now I have a hole.Bummed.Not sure how old these headers are. Im wondering if this was just normal metal fatigue from years of use with water. I only had the outside coated.
    Do you thin Ill be ok to just have this welded up? I know it won't look pretty but Im planing on a recoat or replacment in the off season. Just want to make it through the end of summer...

    Wow that sux prob isnt the only one ready to crack out, id find another set before fixing those and recoating.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Just get it welded for now. I've done that many a time getting a set thru the season. Don't bother recoating or trying to save them long term, once you see one crack others are not far behind.

    Yep found a crack on the otherside too. Just wish I would have known before I spent the cash on the coating.Going to weld it, run it and start shopping for new stainless ones.

    it's metal, not wood. add some, remove some, re-finish.

    find a local fabricator.

    Got a buddy welding the cracks up for this weekend. Question, if I go with new Bassetts or Rewards , will I run into this again running them dry? Not interested in running water injection. Is it a heat issue? Or just my old headers coming to the end of their life span? Just want to know before I sell a kidney, one of my kids and my left nut to get a set of stainless made instead ...

    How many times have they been coated? It's possible they are really thin from being blasted so many times

    That could be. I beleive I was the only one to have them ceramic coated . When I got them, they were chrome and in great shape. Blued perfectly just to the water injection ports, no cracks or rust however, not sure if they had been rechromed along the way. I just wonder if running them dry was just too much at this point in they'er life span. However old that might be? I would have thought they could handle it..

    The internal strain generated from thermal cycles, where a significant delta-T builds up across the metal (ANYWHERE across the metal) will eventually tear these apart. Even stainless or Inconel. Wherever you have bigger delta-T's across the metal, such as the bend right outside your exhaust port, you will have bigger strains. You can patch with weld, but the welding process does the same thing to the metal. So you'll end up cracking it near the weld patch. If you stripped them and sent them to a heat-treat shop to have them stress-relieved (after they're patched), you might get some more life out of them. But it sounds like they are finished, to me. My 2 cts.
