Well, it seems that the constant reoccurrence of an exhaust leak stemmed from a pulling exhaust stud. I'd tighten it, the noise would go away, come back, rinse, repeat.
A couple of weeks ago I took her out for a spin, heard that sound, and got under after cooling to see what the deal was. A quarter turn later, the stud dropped right out. So I'm gonna do an EZLOK insert, and pray. Pics to follow, along with any tips, snags, or bonifide cuss sessions. The fun never ends Right Joe? (IMG:style_emoticons/default/hissyfit.gif) |

Don't let anyone fool you, it's not that hard. I did three at once. Mark the bit depth, and drill at the exact same angle the original stud was at. If you can, use some kind of drilling lubricant - Harbor Freight sells a good foaming kind that won't drip out.
I know that others here have far more experience than I do, but personally, I wouldn't worry about the step stud. If THAT one pulls out, you won't have enough aluminum left to tap the hole for a Time-Sert/EZ Lok. If you install a Time-Sert (which I would recommend) the first time correctly, with red Locktite, you won't have to do this job again later. Sounds intuitive, but some may not know this - you must remove the heat exchanger first so you can see what you're doing. |

Did I hear that right? Oof. Really? That's why I'm not painted. |
