I have a 2.0 type IV from a 914 in my 912, it has the GA heads and Weber 40 IDFs. Today I was warming it up to change the oil and saw flashing from the intake manifold/head seal area when small backfires occured. Naturally I started to tighten the intake manifold bolts. On the #1 cylinder outboard nut, I felt too much play. I wiggled the stud and pulled it right out!
See the picture below. I was able to find more threads in the hole and thread it back in using 2 nuts so it isn't completely stripped. Only about 1/4" of threads came out with the stud. What should I do here?  |

In my experience, the aluminum threads that come out with the stud tend to stay on the stud. Makes the end of the stud look shiny and relatively smooth. Also, I think I can see gaps in between the threads, which make me think it's a coil.
Not that my experience compares to the Cap'n's, but I may be better at stripping threaded holes than he is. (IMG:style_emoticons/default/wink.gif) --DD |

Does anyone know the proper length for the studs that have the flat machined section and also where to get them? Pelican turned up nothing. |
