 broken bolts
If you are going to restore the truck, then why would you hesitate to remove the exhaust manifolds? Taking them off is the easy part. Drilling out the bolts is the hard part.
Take them off, center punch the bolts(three on each side), drill out with a small bit(maybe 1/8), then repeat with a bit slightly smaller than the bolt(the bolt is about 3/8 to 7/16. Use an easy-out to remove the rest of the bolt and threads(after applying some PB Blaster rust remover.
The mechanism on the pass. side is a heat riser. It can be left in(if it works-usually not) or removed. If removed, a spacer man need to be inserted to take up the space.
Not a big deal, just a lot of elbow grease. Be sure to replace the exhaust gaskets and "O" rings. (And paint the exhaust headers with heat paint before installing to give a finished look) |
