Thanks. There is nothing left of the stud, so it will need to be replaced. Is it a screw in or press in and are they available? Things are in the tear down phase, so theses manifolds need to be disassembled, shot peened, studs replaced And ensure that the flap valve is in working order too,….before assembly. Thanks for the pointer on the inter manifold bolt tightening,…before installing.
