Exhaust Manifold Bolt Sheared!
Has anyone had one of their manifold bolt shear off? I heard the dreaded tick, tick, tick and thought it was the up pipe doughnut. After looking at the up pipes, I didn't see any soot that you would expect. Instead, I found soot on the manifold. I thought I just needed to tighten the bolts and discovered one was gone.
How difficult is it to remove the stud from the block? This may be one of the things I pay someone to do as I'm not sure how hard it is. Also the stud is below the hole so I can't get anything on it. I'm not sure what would cause the bolt to shear because it happened while I was driving.
