    I am new to the forum and apologize I am not sure where to post this.

    I took the manifold off to clean intake and throttle body. When i was putting the throttle body back on, I think i overtightened one of the stud bolts and now it just spins. Is there a way to replace the studs on the intake manifold?? I am not sure what do to besides ordering another intake manifold. Any advice would greatly be appreciated!

    You need an E6 Torx socket for the studs. Still, what is it that's spinning? The stud screws into an embedded insert in the intake manifold: is that the thing that's broke loose? Maybe you could bond that with 2 part epoxy??

    Here's a pic, is it the embedded brass-coloured bit (flagged) that's loose?

    The torque value for the throttle body nuts/bolts is 7 ft/lb, see attached.

    The OP probably has to resolve that issue or the engine will be likely to have a vacuum leak.

    Thanks everyone for your help...I am waiting until this weekend to take it apart. I definitely overtightened the studs after seeing the torque specs lol...I believe that the embedded insert is what is broken, if so I will definitely try the epoxy. Do you have any recommendations for which epoxy?
