exhaust manifold bolt cutt off
exhaust manofold problem on 1990 Nissan Stanza
Is this a question?
I presume the exhaust manifold bolts securing the the manifold to the cylinder head or the manifold to down pipe studs have broke. The broken stud needs to be carefully drilled down the center of the bolt or stud and an easy out or left handed drill bit is then used to extract the broken bolt. Working space is restricted, things may need to be removed to get access to the broken stud, and patience and a 90 degree drill or cut down drill bits may be needed. It is an art but we run across it all the time.
