I traced a small exhaust leak to rear of the head where I found the manifold mount stud sheared off. So I gotta remove the manifolds to repair the stud... I have the service manual and it mentions replacing the o-rings on the fuel feed and return lines, and the exhaust pipe donut... Obviously I'll use a new manifold gasket.
I hope to gather all the parts before I tear it apart... Should I expect to replace any other parts such as injector o-rings?... Anything else I should do while everything is apart?
TIA - Joe
