Exhaust leak

[gmonroe]

I bought mine used and it had the same thing. But the stud was already snapped off. I tried to get to it with the manifolds off but no luck. Had to pull the head. Slapped on some shorty headers while I was in there. I STRONGLY urge you to change the knock sensors when you do this job. TRUST ME. Its a cheap part and you will be right there when you do it. (I learned the hard way. My knock light came on like 2 days after putting it all back together.)
