All of my header bolts on both sides were loose for a while. I got most of them tightened, but there are a few that I cannot tighten because, as far as I can see, it's physically impossible. A ratchet is far too big to fit on there, and a wrench won't clear the header tubes.
The valve is ticking, so I'm basically positive that there's SOMETHING wrong with the valve. In addition to the nasty exhaust smell on the driver's side exhaust pipe only, the compression on cylinder 8 is only 125 psi.
