I've been noticing what sounds like a slight exhaust leak, or possibly the Hemi tick, IDK. Decided to check the header bolts, they were all snug. A few of them I could turn 1/4 or so, then I got to the last one (front top passenger side). As soon as I put the ratchet on it, I said aha, that's the problem. It was lose so I began to tighten it. Then I said wow, this thing must have been ready to fall out. As I continue, I get this sinking feeling in my gut because it wouldn't get tight, WTF. So I backed it out to find a coil of aluminum around the threads - STRIPPED! The guy who installed the headers (2 years ago) must have stripped it and didn't tell me. :VHOT: So I removed the lock washer which allowed the bolt to go little deeper into the head, and I got it snug. Not sure if it will stay in place without the lock washer, but I don't think the hole can be tapped without removing the head. Any suggestions?
